Introducing the System Matrix offers the Voice over IP-Analog Telephone Adaptor, VoIP ATA or Matrix Phone Adaptor (SETU ATA2S) which is a SIP based VoIP product. Sending voice signals over the Internet is called Voice over IP or VoIP. Session Initiated Protocol, SIP is an internationally recognized standard for implementing VoIP. VoIP-ATA is an Analog Telephone Adapter that allows a user to make voice call over IP network using a conventional telephone instrument. VoIP-ATA has one IP port, for WAN connection. WAN port is used to connect VoIP-ATA to the Internet using broadband modem, cable modem, router, etc. The VoIP calls are made through WAN port. VoIP-ATA has two FXS ports to which conventional telephone instruments (SLTs) can be connected. Call routing mechanisms for IC calls from IP to FXS and OG calls from FXS to IP are included in VoIP-ATA. The IC call routing mechanism helps the user to route the calls to either or both the FXS ports whereas the OG call routing mechanism helps the user to route the call through desired SIP Account which is helpful when services from two different ITSPs have been taken, each having cost benefit in some terms over the other. When a telephone number (A E.164 number or a SIP number without domain name. i.e. the prefix of the SIP telephone number e.g. Suppose a user with SIP number SIP: 12345@xyz.com is to be called then the caller should dial 12345) is dialed by the user, the VoIP-ATA converts this into an IP call using SIP protocol and makes a call to the callee. Using Phone book, the user can also dial complete SIP number by just dialing feature code and corresponding index number. User can also use Auto Configuration feature if he wants to avail facility of configuration of ATA by ITSP from central location. Refer Feature List which includes important features supported by VoIP-ATA. SETU ATA2S System Manual 15

For this, mechanical drawing can be used as a reference, which is provided end of the chapter. Connect a standard analog telephone instrument to FXS1 and FXS2 ports, using telephone cables provided. Insert one end of the Ethernet cable into the WAN port of ATA and connect the other end of the Ethernet cable to Ethernet Switch which is connected to router or DSL Modem. Insert one end of the Ethernet cable into the Ethernet Switch and connect the other end of the Ethernet cable to the PC. Check the voltage from the power point from where the supply is to be accessed. It should be between 90-265VAC, 47-63Hz. SETU ATA2S System Manual 21

Insert the DC output terminal of power adapter into the Power jack of the ATA and connect the 230VAC pins of the power adapter to a wall outlet for 230VAC. When you power ON the ATA, observe that all LED s are ON for few seconds and then SIP1, SIP2 LED s are flashing. Basic Steps for Configuration WAN Port: Default WAN IP Address for ATA is 192.168.001.151. ABSOLUTELY NEEDED! Use WAN IP Information from your LAN Admin. or ISP IP Address (must) IP Mask (must) Gateway DNS IP Address (must) DNS Domain Name Note that subnet of WAN and Internet (Router) are same. Read the IP of PC, by clicking on Network Neighborhood Properties TCP/IP Connection Properties for Windows98. Choose the unique IP address of the PC such that its subnet is same as subnet of IP address of ATA, provided by ISP. PLEASE CHECK! The subnet of your PC IP Address must be same as of ATA. For example, if IP address of ATA is 192.168.5.10, then PC IP Address port should be programmed as 192.168.5.X. where X can be any number from 1 to 254, except 10. By doing this, subnet remains same. Pick up the handset of the analog phone connected to ATA. Enter the programming access code #19 followed by password 1234. You get programming tone. Enter the WAN IP Address, using command 11-<WAN IP Address>-#*. For e.g. to enter IP Address 192.168.001.151. Enter command 11-<192168001151>-#*. You get confirmation tone followed by system restarting. 22 SETU ATA2S System Manual

Start Internet Explorer (IE6 with SP2, Service Pack) of PC connected to the Ethernet Switch. Type in the IP Address programmed above in the Address field. On the login page, enter default password 1234. Click on SIP Account from the menu provided on left side of the web page. Get Information from your ITSP for SIP Account SIP ID Registrar Server Address Registrar Server Port Authentication User ID Authentication Password Outbound Proxy Server Address Outbound Proxy Server Port Enter above information in SIP Account1 field. If these information is not available, keep the values as default. For e.g. Registrar Server Port = 5060. Enable SIP Account for SIP1 and also enable Outbound Proxy, if information is programmed. If you have a second internet phone Service Account (SIP2), then use above fields for SIP2 port and enable. It allows you to use second phone (or Fax) connected at FXS2 port. Submit page. You can have a look at all above parameters and software version information by clicking on Status from the menu. ATA is ready for further IP calling service! User can also use Auto Configuration feature if he wants to avail facility of configuration of ATA by ITSP from central location. Refer Appendix A: Troubleshooting or default the system and start again, if you cannot establish connectivity from your ATA. Making Phone Calls After SIP1 and/or SIP2 LED is ON, just dial the SIP ID numerical number e.g. 4567 which is registered to the same ITSP provider. If SIP account is 4567@provider.com then the SIP ID number is 4567 and SIP service domain is Provider.com. SETU ATA2S System Manual 23

PSTN number can be called directly, to the area which your ITSP Service Provider supports. You can also use feature of Speed Dialing and Peer-to-Peer Calling as explained below: Speed Dialing: The numbers which you need to dial frequently can be programmed in the Phone Book table. Suppose the number you want to dial is entered at index 05 of the phone book, then go OFF- Hook and dial #8-05. The number will be dialed! Peer-to-Peer Calls: Peer-to-Peer number can be dialed even if ATA is not registered to any service provider. If Peer-to-Peer is enabled and FXS port number is programmed, you can call another ATA by dialing its FXS port number. You can also call another ATA or IP- Phone by dialing its IP Address if Peer-to-Peer is enabled. For e.g. Just dial 192*168*1*21, to call the IP number 192.168.1.21.

Section 2: Features and Facilities

Auto Configuration Matrix ATA configuration includes some basic settings like Registrar Server Address, Authentication user ID, and User Password which are provided by the Service Provider (ITSP). Also some special services like Call Forward are provided by the ITSP. Hence, it is desirable that the ATA is configurable by the ITSP from the central location. Matrix ATA supports this by providing Auto Configuration feature. The ITSP will keep the folders of configuration files in Central Server for different ATA units as per LAN/WAN MAC Address number of the ATA. When the customer connects the ATA to the ITSP s network, the ATA gets automatically configured and the customer starts using the services. How it Works? ATA makes use of TFTP server to down load the configuration files. User has to just enter the Server Address provided by ITSP and specify the config. Folder path provided by ITSP, in the Web page for Auto Configuration. Then after selecting option for using the feature at power ON, Click on submit the page. Three options for using the feature are provided: User can select that the ATA is not to be configured provided as default. User can select that the ATA is to be configured, whenever it is switched ON. User can select that the ATA is to be configured, when switched ON next time. ATA can get the Address of FTP Server from the DHCP Server also if FTP Server Address is not programmed in ATA. The MAC Address displayed on the Status Page is programmed at the factory and can not be changed or deleted by the user. If the FTP server address is not found, the auto-configuration process is aborted and the default configuration files or the current ones are used by the ATA. If all the required files are not available in the folder, then there will be incomplete configuration download to the ATA. Also only those downloaded files whose version will match to the version of ATA will SETU ATA2S System Manual 29

be updated. For example, 7 configuration files are necessary and if only 5 files are present, then these 5 files only will be downloaded by the ATA and will be updated in ATA which may not meet the required Configuration of the ATA. When Auto Configuration is complete, the Status page displays following information: In Status field suitable message is displayed such as: No Tftp Server Specified Auto Configuration Fail Auto Configuration Success In Statistics field, suitable message regarding how many files are down loaded successfully and total number of configuration files are provided by the system. For example, if X=Number of files down loaded and Y=Total number of files updated. Then the message displayed will be as: Files Downloaded/Configured = X/Y How to program?

Important Points: ATA will not restart, if user clicks on Submit on this page. This feature can also be used when ATA is connected to an IP PBX. Relevant Topic: 1. Status 66 =X=X= Matrix SETU ATA2S System Manual 31

Dial Plan Generally Matrix ATA user can assign two SIP Account numbers to two FXS Ports, one for each. Hence if Call from FXS1 needs to use SIP2 Account, then it can be done by assigning SIP2 to FXS1 in the FXS Port parameters screen. But the ATA has also facility to allocate SIP account, as per the number dialed. The database for this mapping is called Dial Plan. Dial Plan has in all 10 entries. Each entry has a number and corresponding SIP account which the system will use to make an OG call. If the number string dialed by the user matches with any of the number string in the Dial Plan, the call is made using the corresponding SIP Account. This flexibility is helpful in following case: Example: If Numbers are mapped with SIP Account as given below: Index Number SIP Account 01 1234 SIP1 02 12 SIP2 : : : 10 Then, a person in the Cyber cafe can call to Africa on 1267 even if another person is talking to US on SIP1 Account on 1234 number. The ATA allocates SIP2 account to the person who wants to call Africa, based on closest best fit criteria. Thus Dial Plan works as powerful routing tool. Similarly, if the user dials a number say 1256783, the call should be made using SIP2 as this number best fits with the number string in index 02. If entries are not matching or the table is blank, the OG call will use default SIP1 Account. Click on Dial Plan. 32 SETU ATA2S System Manual

FXS Port Introduction: For efficient interfacing with Analog telephone connected at FXS1 and FXS2 and for efficient use of many features like Echo cancellation, VAD, etc., some parameters are programmed on FXS port. This chapter gives detailed procedure of programming. The ATA supports only DTMF dialing (Tone Dialing). ATA supports four types of Caller Number Presentation viz. None, DTMF (not in this version), BellCore FSK and V.23 FSK. ATA supports Calling Party Control to disconnect the Trunk which is still busy when remote called party has gone ON-Hook. It is implemented by: CPC period of 500 Millisecond. ATA supports programming at Input Gain (-6dB to +6dB), Output Gain (-6dB to +6dB), Programmable Flash Timer, Forward Error Correction, Programmable Ring Timer, Programmable Inter-Digit Timer and fixed First Digit Wait Timer. Some parameters are described as below before explaining programming: FXS Port Name: This name is sent to the callee in the Display Name field in the SIP call. The callee shall be able to identify the FXS port from which the call is made along with the SIP number provided by the ITSP for the SIP Account. To elaborate: Suppose the ITSP has provided a SIP number 1234@abc.com. When the call is made by FXS1 or FXS2, the callee gets the same number. Hence he is unable to identify that who is the actual caller; FXS1 or FXS2. The Station name feature resolves this problem by assigning xyz name only to FXS1 and calling from port FXS1. FXS Port Number: It is used for Peer-to-Peer calls only. Call Progress tone: Different types of tones are played during specific event of establishing the call, speech duration and termination of the call. As per ITU standard these tones are of different specification for different country. For example, Dial Tone for India consists of 34 SETU ATA2S System Manual

400Hz modulated by 25Hz, but for USA/CANADA, it is 350+440Hz, without modulation. Based on specific frequency, modulating frequency and cadence, tones are categorized as shown below: Dial Tone Ring Back Tone Busy Tone Error Tone Confirmation Tone Programming Tone CO Call Waiting Tone (CCWT) ATA plays the Dial Tone when it is ready to accept the first digit of a remote address to make an outgoing call. Normally played when FXS goes OFF-Hook. ATA plays the Ring Back Tone when the called device is alerting the callee. ATA plays the Busy Tone when the callee is busy. ATA plays Error Tone when, there is no registration with proxy server or user has performed some wrong operation. It remains for 7 secs. But when it is used as Error Tone due to invalid programming, then it remains for only 3 secs. and it is called Programming Error Tone. ATA plays Confirmation Tone, to indicate that valid command is received by the system and it has taken necessary action. ATA plays Programming Tone which, prompts the user to enter fresh commands during programming. This tone, remains continuously till user dials digit 0. But ATA plays this Programming Tone as Feature Tone when user has activated some feature like Call Forward, Do Not Disturb (DND), etc. and it remains for 7 secs. ATA plays the CCWT when an incoming call arrives while the user is connected to another party. The time duration and the tone, when it is matured are as per following table 1: SETU ATA2S System Manual 35

Name Timer (Sec.) Matures to Dial Tone 7 Error Tone Standby RBT 60 Error Tone Standby Busy Tone 30 Error Tone Standby Error Tone 7 Error Tone Standby Confirmation Tone 3 Dial Tone/Feature Tone Programming Tone 7 Error Tone Standby CCWT 60 Error Tone Standby Timer column shows that for how long the tone will continue and last column Matured to shows type of tone after timer is expired. It goes in stand by after error tone completes. For example, ATA plays error tone for 7 secs. and then goes in stand by. Refer Table 2 for tone specification for different countries, at the end of this chapter. Just select country name from the list of countries in the Combo Box for FXS1 and FXS2 to program the Call Progress Tone. Ring Type: The Matrix ATA supports different cadence for the ring when incoming call lands on FXS1 or FXS2. These cadence is standardized for different country. For example, India supports: 25Hz, 0.4 ON 0.2 OFF, 0.4 ON 2.0 OFF (Sec.). USA/Canada supports: 25Hz, 2.0 ON 4.0 OFF (Sec.). In order to support a specific ring type, user has to just select the country. The system will select the cadence as per table 3, at the end of chapter. Default country is India. First Digit Wait Timer: First digit wait timer signifies the time for which the system waits for the user to dial something once the FXS port goes OFF-Hook. On expiry of this timer, the system will give error tone to the user. 36 SETU ATA2S System Manual

Internal Digit-Digit Wait Timer: (Timer of Relevance) This is the time during which if user does not dial a digit after pressing a digit, the system stops collecting further digits and processes digits dialed so far. Matrix Echo Cancellation: Line echo is caused when conversion between 4-wire to 2-wire line is carried out, by telephony hybrid. And delay exceeds 50ms. Acoustic echo is caused when our own voice reverberating the phone-receiver when we talk. Echo Cancellation is a technique that allows for isolation and filtering of unwanted signals caused by echoes. The echo canceller-device puts a signal on the return transmission path, which is equal and opposite of the echo signal. Echo cancellers (digital filters) are used depending on the length of the echo to be compensated, also depends on the distance between gateway and line hybrid. (Between 8-32ms for SOHO products) VAD: Voice Activation Detection (VAD), is a software application that allows a data network carrying voice traffic over the Internet to detect the absence of audio and conserve bandwidth by preventing the transmission of silent packets over the network. Most conversations include about 50% silence. VAD (also called silence suppression ) can be enabled to monitor signals for voice activity so that when silence is detected for a specified amount of time, the application informs the Packet Voice Protocol and prevents the encoder output from being transported across the network.

Jeeves What s this? As, the set up of SOHO and Enterprise is normally equipped with WAN and Router on the Internet line, it is very convenient if the device has the capability to be programmed via HTML-based interface. The Matrix ATA has this provision. WWW is an abbreviation of Internet s World Wide Web. Matrix ATA needs Web browser IE6 with SP2 (Service Pack) patch or Mozilla Fire Fox installed on the PC. Description of following features related to web will help in programming the system. IP Address An IP address (Internet Protocol address) is a unique number, similar in concept to a telephone number, used by network devices (computers, time-servers, FAX machines, some telephones) attached to a network to refer to each other when sending information through a WAN or the Internet for example. This allows devices passing the information onwards on behalf of the sender to know where to send it next, and for the device receiving the information to know that it is the intended destination. An example of IP address is 207.142.131.236. Converting a number address to a more human-readable form called a domain address is done via the Domain Name System. The Internet Protocol (IP) knows each logical host interface by a number, the so-called IP address. On any given network, this number must be unique among all the host interfaces that communicate through this network. Users of the Internet are sometimes given a host name in addition to their numerical IP address by their Internet service provider. For all programs that utilize the TCP/IP protocol, the sender IP address and destination IP address are required in order to establish communication and send data. Sub Net It is a mechanism that is used to split a network into a number of smaller sub networks. It can be used to reduce traffic on each sub network by confining traffic to only the sub networks for which it is 44 SETU ATA2S System Manual

intended, thereby eliminating issues of associated congestion on other sub networks and reducing congestion in the network as a whole. Makes entire network more manageable. Each sub network functions as though it was an independent network, keeping local traffic local, and forwarding traffic to another sub network only if the address of the data is external to the sub network. Such decisions are made on the basis of routing-tables contained within the various routers, with each table comprising an IP address table. Subnet is a portion of the network, which may be a physically independent network, which shares a network address with other portions of the network and is distinguished by a subnet number. Default Gateway A default gateway is a node on a computer network that serves as an access point to another network. In enterprises, the gateway is the computer that routes the traffic from a workstation to the outside network that is serving the Web pages. In homes, the gateway is the ITSP that connects the user to the internet. A default gateway is used by a host when an IP packet s destination address belongs to someplace outside the local subnet. Domain Name System (DNS) DNS is a system that stores information about host names and domain names in a type of distributed database on networks, such as the Internet. Of the many types of information that can be stored, most importantly it provides a physical location (IP address) for each domain name, and lists the mail exchange servers accepting e-mail for each domain. The DNS provides a vital service on the Internet as it allows the transmission of technical information in a user friendly way. While computers and network hardware work with IP addresses to perform tasks such as addressing and routing, humans generally find it easier to work with hostnames and domain names (such as www.example.com) in URLs and e-mail addresses. SETU ATA2S System Manual 45

The DNS therefore mediates between the needs and preferences of humans and of software. Dynamic Host Configuration Protocol (DHCP) The DHCP is a client-server networking protocol. A DHCP server provides configuration parameters specific to the DHCP client host requesting, generally, information required by the host to participate on the Internet network. DHCP also provides a mechanism for allocation of IP addresses to hosts. The DHCP protocol provides three methods of IP address allocation: Manual Allocation. Automatic Allocation. Dynamic Allocation. How to configure ATA? To start basic VoIP configuration first enter the default WAN IP address of the ATA, obtained from SE in the Address bar of the Webbrowser screen as explained below: Launch the Web browser as explained below: Double Click on Internet Explorer icon Or Click on Start Programs Internet Explorer. Enter IP Address at Address Bar after confirming from SE. Let us say IP Address 192.168.1.10 is entered at Address Bar on opening page of Microsoft Internet Explorer. Note that Matrix ATA2S default IP Address is 192.168.001.151. ATA displays Welcome page with a field for entering Password.

Peer-to-Peer Calling Matrix What s this? ATA can call another user agent (ATA or Softphone), which is in the same network (figure 2) or which can be in another network, which is connected by virtual LAN (VLAN) provided by ITSP (Figure 1). For example, ITSP provides VLAN services to connect two offices situated in different cities. ATA can call to an extension number of some other ATA or soft phone without going through any proxy. This is known as Peerto-Peer Calling. For this, the extension number (FXS Port number), which is to be called, is programmed in the number field and IP address of the called ATA is programmed in IP Address field of the Peer-to-Peer Call Table. Each entry has two parameter viz. Number and IP Address. For example, if IP address of ATA which is to be called, is 192.168.1.12 and extension number 3005, then at Index 01, 3005 is programmed in Number field and 192.168.1.12 is entered in IP Address field and screen is Submitted. For Peer-to-Peer OG Call, user has to follow following steps: Enable Peer-to-Peer in FXS Port screen. Dial 3005. For incoming Peer-to-Peer call (IC Call), the FXS port number on which call is to be received, is programmed in FXS Port number field on the screen FXS Port. For example, if 4001 is programmed in FXS Port screen in FXS1 column then any IC call on 4001 will land on FXS1 port. But, if incoming call doesn t have perfect match and only IP Address of Matrix ATA is called, then call will land on both FXS1 and FXS2. ATA also supports to call the ATA by an IP number. After lifting the handset, user dials digits with * in place of.. This is called Direct IP Calling feature. This feature is very much useful in case, Party s IP Address only is known and not SIP-ID. For example, a PC phone, with its IP Address 192.167.1.21, as shown in figure 1 can be called by just dialing 192*167*1*21, after lifting the handset. SETU ATA2S System Manual 55

Software Upgrade What s this? ATA support an embedded FTP server which can be used for: Uploading/Downloading System files File Transfer Protocol (FTP), a standard Internet Protocol, is the simplest way to exchange files between computers on the Internet. Like the Hypertext Transfer Protocol (HTTP), which transfers displayable Web pages and related files, and the Simple Mail Transfer Protocol (SMTP), which transfers e-mail, FTP is an application protocol that uses the Internet s TCP/IP protocols. FTP is commonly used to download program and other files to your computer from other servers. Pop-up should be enabled from; TOOLS-Popup Blocker on the Internet Explorer. Procedure to upgrade file: To upgrade any file of the ATA software, click on S/W Upgrade. Four file folders are displayed: appli, config, driver, httpd. Modified file from User s Page is copied in the suitable file folder, config, driver or httpd. Old file is automatically replaced. To upgrade an appli file, first old one must be deleted and then new file is copied. Finally ATA has to be restarted for applying new file application. Mozilla-Client will not work for upgrading the Software. Relevant Topics: 1. Password 54 2. Jeeves 44 =X=X= SETU ATA2S System Manual 65

Status What s this? ATA user may require to view remotely for WAN Addresses and registration status. Matrix ATA has this facility. The registration time is provided by the server. User can quickly have a glance for WAN address and can change it from respective page, if required. It also provides Registration Status which is useful to know whether SIP is registered or not. For example, if the Ethernet cable for Internet gets disconnected than after some time, Registration Status is displayed on the Status screen (if updated) and user can take corrective action, just by connecting the cable instead of restarting the system.

Supplementary Services This chapter contains following sections: Introduction Programming Type Programming of Web Pages Programming using Phones Important Points Introduction: ATA provides following call features based on supplementary services provided by the ITSP: Making Second Call Call Hold Call Waiting Call Toggle Call Transfer-Blind Call Transfer-Attended 3-Party Conference Call Forward-Unconditional Call Forward-On Busy Call Forward-On No Reply DND Caller ID These supplementary services should be supported by the service provider. Making Second Call Telephone user can make second call while talking to first caller by keeping the first caller on hold. The user should keep the first caller on hold and then dial the destination number to which he wants to talk. On completing the talk, ask the called party to hang-up. When the called party hangs up, the user gets connected to the first caller. Also, while in speech with second call, he can talk to first user by using call toggle access code (except type 3 users). The user can also have conference between three parties by dialing conference access code. 70 SETU ATA2S System Manual

Call Hold Call Hold allows one party to maintain an idle (non-talking) connection with another party while receiving another call (Call Waiting) or while initiating another call (Call Transfer), or while performing some other call management functions. Call Waiting Call Waiting (CW) notifies an engaged caller of an incoming call and allows them to receive a call from a third party while the party with whom they have been speaking is put on hold. Call Transfer (Blind): Call Transfer allows one party to reconnect the party with whom, they have been speaking; to a third party. The first party is disconnected when the third party becomes connected. Call transfer without consulting to the party on whom call is to be transferred is Blind Transfer. Call Transfer-Attended Telephone user dials Call Hold access code followed by the Transfer target s number to transfer the caller (Transferee) to the Transfer target. In case of, Call transfer with consulting or Call Transfer-attended the user gets ring back tone followed by speech or Busy Tone. He may talk to transfer target and hang up. Call Toggle To attend to the second call, phone user has to use this feature by dialing Call Toggle Access Code. When the user dials the Call Toggle access code when a party is held, user is connected to the waiting caller. If no party is held, then user gets error tone. The user is connected to the current party when he goes ON-Hook, gets ring and again goes OFF-Hook. Type 3 user cannot use this feature. 3-Party Conference Telephone user dials Conference access code to have Conference between the User and the two callers. When the user dials the Conference access code (with one held SETU ATA2S System Manual 71

party and one current party): Conference is held between the user and the two callers. While during the Conference if the user dials the access code to Toggle (Not applicable for Type 3 users). User is connected to one of the callers. Other caller gets music.

Procedure of Calling: Call Forward Call Forwarding (Always) Incoming calls may always be forwarded to another designated party, and call forwarding founder can hear the notified rings. Example: 1 A calls B. NO TALK. 2 3 B responds: it is unavailable. So it returns a forwarding destination C. A is automatically forwarded to C. User at A is unaware of this. Talk between A, C. Matrix Call Forwarding (Busy): Incoming calls can be forwarded to another designated party if the phone of the called party is busy. 1 A calls B. NO TALK. 2 B responds, (Busy state). B is in busy state and the new forwarding state is C. 3 A is automatically forwarded to C. Talk between A, C. Call Forwarding (No-Answer): Incoming calls can be forwarded to another designated party when there is no response, from the original called party. B is ringing, A can hear 1 A calls B. ring back tone. 2 3 B responds to A, after 45 secs. (programmable) with no one picking up the phone. A is automatically forwarded to C. No answer and A needs to contact C. Talk between A, C. SETU ATA2S System Manual 75

VoIP Basics Matrix VoIP is the sending of voice signal over Internet Protocol. Calling on VoIP allows user to make phone calls and send faxes over the internet at a negligible cost compared to the normal circuit switched Telephone network. The main components of VoIP are: SIP Network Servers RTP NAT and STUN Types of NAT STUN Outbound Proxy SIP ALG SIP Call Flow Important Voice Parameters: Jitter Buffer, Voice Compression and QoS. SIP: The signaling protocol which is used to establish an IP call is called SIP-Session Initiation Protocol. It is an application layer protocol that handles the setting up, altering and tearing down of voice and multimedia sessions over the internet. Refer RFC 3261 for more information. SIP handles telephone calls and can interfere with PSTN network. A SIP account uses complete identity called, URI (Uniform Resource Identifier) or SIP Address, like e-mail address and is given by: SIP-Number@SIP service Domain. SIP number can use letters or numbers like vrajeshp@itsp Provider.com or 73121@ITSP Provider.com. A SIP service domain is the domain name in the SIP URL. For example, if SIP address is 73121@VoIP Provider.com, then VoIP Provider.com is the SIP service domain. In general, SIP follows the Client-Server Architecture. To support this, there are two main entities-user agent and network servers. The peers in a session are called User Agents (UAS). A user agent can function in one of the following roles: User agent client (UAC)-A client application that initiates the SIP request. SETU ATA2S System Manual 83

User agent server (UAS)-A server application that contacts the user when a SIP request is received and that returns a response subject to user s input. Network Servers: There are three types of network servers in a SIP network: proxy server, redirect server and registrar server. Proxy Server: A SIP proxy receives a request, makes a determination about the next server to send it to, and forwards the request, possibly after modifying some of the header fields. As such, SIP requests can traverse many servers on their way from UAC to UAS. Responses to a request always travel along the same set of servers the request followed, but in reverse order. Redirect Server: The redirect server does not forward requests to the next server. Instead it sends a redirect response back to the client containing the address of the next server to contact. SIP Registrar: SIP Registrar is an entity where SIP users can get themselves registered. Registrar imparts mobility to the SIP users. A SIP user can register himself with a registrar. If the user changes his location, he has to register again with the registrar stating his latest contact information. Whenever a call is to be delivered to that user, Registrar can provide the information about the location where the user was active recently. RTP: After a VoIP call is established using SIP, the RTP (Real Time Protocol) is used to handle voice data transfer in the packets form. Refer RFC 1889 for more details. NAT and STUN: NAT (Network Address Translation-RFC 1631), is the translation of IP address of a host in a packet. For example, the source address of an outgoing packet, used within one network is changed to a different IP address known within another network. 84 SETU ATA2S System Manual

For using this feature, two terms are explained as below: a. NAT b. STUN One network is designated the inside network and the other is the outside. Typically, a company maps its local inside network addresses to one or more global outside IP addresses and unmaps the global IP addresses on incoming packets back into local IP addresses. This helps ensure security since each outgoing or incoming request must go through a translation process that also offers the opportunity to qualify or authenticate the request or match it to a previous request. NAT also conserves on the number of global IP addresses that a company needs and it lets the company use a single IP address in its communication with the world. Types of NAT: Four types of NAT s can be used: Full Cone NAT-This type of NAT maps all requests from the same internal IP address and port to the same external IP address and port. Any external host can send a packet to the internal host only if the internal host had previously sent a packet through the NAT. Restricted Cone NAT-This type of NAT maps all requests from the same internal IP address and port to the same external IP address and port. An external host (with IP address X) can send a packet to the internal host only if the internal host had previously sent a packet to IP address X. Port Restricted Cone NAT-This type of NAT maps all requests from the same internal IP address and port to the same external IP address and port. An external host (with IP address X and source port P) can send a packet to the internal host only if the internal host had previously sent a packet to IP address X and port P. Symmetric NAT-In a symmetric NAT, all requests from the same internal IP address and port to a specific destination IP address and port are mapped to the same external IP address and port. If the same host sends a packet with the same source address and port, but to a different destination, a different mapping is used. Furthermore, only the external host that receives a packet can send a UDP packet back to the internal host. SETU ATA2S System Manual 85

STUN: (RFC 3489) Note: STUN is used if there is a NAT router between ATA and SIP Server (from ITSP). STUN stands for Simple Traversal of UDP over NAT. It is a protocol, which enables an IP phone to detect the presence and type of NAT behind which the phone is placed. An IP phone that supports STUN can intelligently modify the private IP address and port in its SIP/SDP message by using the NAT mapped public IP address and port through a series of STUN queries against a STUN server located on the public Internet. This will allow SIP signaling and RTP media to successfully traverse a NAT without requiring any configuration changes on the NAT. STUN presents a working solution for most NATs that are not symmetric NAT, e.g., most of the SOHO routers have non-symmetric NAT and in this case, it is OK to use STUN. However, STUN does NOT work with symmetric NAT and if your routers have built-in symmetric NAT, do not use STUN. A STUN server can help facilitate traversing through most NATs, except for symmetric NATs. Outbound Proxy VoIP service provider can host a SIP outbound proxy server to handle all of the ATA s VoIP traffic. User has to enable this feature if VoIP service provider has a SIP outbound server to handle voice calls. This allows the ATA to work with any type of NAT router and eliminates the need of STUN. SIP ALG Some NAT routers includes the gateway which allows SIP calls to pass through NAT by checking and translating IP addresses embedded in the data stream to Public IP addresses. This type of NAT is known as SIP ALG, SIP Application Layer Gateways. If ATA is behind ALG, it eliminates need to use STUN or Outbound Proxy for NAT traversal. SIP Call flow: A simple example of how SIP requests and responses are sent will help understanding SIP and RTP. 86 SETU ATA2S System Manual

When A calls B, the steps for the set up and tear down of a SIP call is explained as below: A B 1. INVITE 2. Ringing 3. OK 4. ACK 5. Voice Data-RTP 6. BYE 7. OK 1. A sends SIP INVITE request to B. This message is an invitation to B to participate in a SIP telephone call. 2. B sends a response that it is ringing. 3. A answers the call. B responds it by OK. 4. B also answers the call and A sends acknowledgment by sending ACK message. 5. Now, voice session starts between A and B in form of RTP (Real Time Protocol). 6. After the talk, A hangs up and sends a BYE request. 7. Finally, B sends the reply by sending OK response and the call is terminated. Important Voice Parameters: Jitter Buffer: The clarity of voice heard from the called party is also distorted due to non-uniform delay introduced by the Telephony network known as Jitter. In order to reduce the effect of jitter, some sort of filters are used in the voice-channel called Jitter Buffer. The ATA has built-in adaptive buffer that helps to smooth out variations in delay (jitter) for voice traffic. This will ensure good voice quality. It is not programmable. Voice Compression: Voice compression is a technique to reduce the band width of voice channel, using suitable codec or Coder-Decoder. The codec SETU ATA2S System Manual 87

converts voice signals from analog form to digital signals and vice versa. It uses the compression alongwith, CELP. Compression-decompression is a voice compressiondecompression algorithm that defines the rate of speech compression, quality of decompressed speech and processing power requirements. It is called companding. Codec of suitable bandwidth is selected during the speech reception or transmission, to minimize the digital voice channel bandwidth. QoS: Quality of Service, QoS is the capability of a network to provide better service to selected network traffic over various technologies, including Ethernet and 802.1 networks, and IP-routed networks. ATA supports Type of Service tagging and Differentiated Services tagging as mentioned below: (This allows ATA to tag voice frames so they can be prioritized over the network). 1. Type of Service (ToS) 2. DiffServe ToS: Network traffic can be classified by setting the ToS values at the data source (at the ATA) so that a server can decide best method of delivery, such as the least cost, fastest route etc. This parameter allows you to configure Type of Service (ToS) bits by specifying the precedence and delay of audio and signaling IP packets. DiffServe: DiffServe is differentiated Services, which defines a Class of Service model that makes packets so that they receive per hope treatment at DiffServe-compliant network services along the route, based on the application types and traffic flow. Packets are marked with DiffServe Code Point (DSCP) indicating the level of service desired. Relevant Topic: 1. Glossary 104 =X=X= 88 SETU ATA2S System Manual

WAN Explanation What is this? This chapter explains programming aspects of WAN ports, in detail. If you have already started programming using chapter Getting Started, do not use this information. ATA has facility to program WAN port by normal phone as well as the computer. For this, DHCP server used in the LAN is also discussed. For more details on IP and DHCP refer Glossary and Jeeves topics. How to program? Configuring the ATA ATA has a WAN port whose IP address is 192.168.001.151 (default). The WAN port of ATA can be connected to one of the ports of the LAN Switch/Hub/Router (in Corporate Offices) OR it can be connected to the Ethernet port of the Broadband modem (in SOHO). When connected to LAN of the organization, the IP address of the WAN port should be changed according to the LAN addressing scheme. The LAN might be using static addresses or dynamic addresses. If static addresses are used, the SE should take the static address of the WAN port from the LAN administrator and program it as the IP address for the WAN port of ATA. If DHCP server is used in the LAN, then DHCP client should be enabled in the product using the embedded Web server. Doing so, the DHCP server in the LAN shall assign an IP address dynamically to WAN port of the ATA whenever ATA is restarted. The IP address of the WAN port can be configured using a computer as well as conventional instrument. (Please note that, only the IP address of WAN port can be programmed from conventional Phone and no other parameter/feature of the WAN port can be programmed from conventional Phone.) Also WAN IP address is requested from server if PPPoE server is enabled and User Name and Password are entered. Programming are explained with two options as mentioned below: Configuring IP Address of WAN port of ATA using computer Configuring IP Address of WAN port of ATA using conventional phone instrument. SETU ATA2S System Manual 89

Configuring the IP address of WAN port of ATA using Computer Make the connections as shown in the figure given below: WAN Port FXS1 Computer FXS2 SETU ATA2S Get the IP address for the WAN port of ATA from the LAN administrator or ITSP. Open Web browser (Internet Explorer or Netscape) on the computer connected to the WAN port of the ATA. Enter the default WAN port address (192.168.001.151) in the URL field and press Enter. Embedded Web server takes the System Engineer (SE) to the Home page. The SE has to Log in into the ATA using password (default password = 1234). The SE will have to go to WAN port settings link and change the IP address of the WAN port from default to that given by the LAN administrator. The SE may change the Subnet Mask, Gateway address and DNS address if required. Once the new setting take effect the SE will have to re-enter the web server with new URL. Note: Ensure that the subnet of WAN and PC is same. 90 SETU ATA2S System Manual

Configuring the IP address of WAN port of ATA using Conventional Phone Instrument Make the connections as shown in the figure given below: WAN Port FXS1 FXS2 SETU ATA2S Get the IP address for the WAN port of ATA from the LAN administrator or ITSP. Pick up the Handset of the Conventional Phone. You get error tone, since you are not registered. If you are registered, you shall get dial tone. (This is less likely when configuring the ATA for the first time) Enter the Programming Access Code #19 followed by password 1234. You get programming tone. Enter the WAN IP address using following command: 11-WAN IP Address-#* Where, WAN IP Address is of 12 digits. Each octet is of three digits. If only single digit is used then it should be converted to three digits and then entered. For e.g. To enter IP address 192.168.9.10, enter command 11-192168009010-#*. You get confirmation tone for 5 secs. followed by programming tone. SETU ATA2S System Manual 91

Enter 0 to get out of programming mode. The SE can dial any programming command during confirmation tone. Similarly, if ATA is installed in Residences where a HUB or a switch is not used, the static IP address given by the Service Provider should be programmed as the WAN port address. However, if the Internet Telephony Service Provider provides dynamic IP address then also ATA will work and it will be possible to make calls and receive calls through IP network. In this case, the ATA will read the dynamic IP address assigned by the Service Provider s Router and use this address to make the IP calls. It is assumed that the connection provided by the Service Provider will be always available. Important Point: When SIP is not registered or Ethernet cable is not connected, error tone is coming on both FXS ports, but programming by phone is still possible. Relevant Topics: 1. Jeeves 44 2.

WAN Port Matrix ATA is receiving and transmitting data to the Internet Network through Wide Area Network (WAN) port. There are three ways to obtain WAN IP-address as mentioned below. Depending upon type of Internet connection, one of this is used. e.g. if Internet connection is through xdsl (Digital Subscriber Loop), PPPoE is selected. By manually entering a static IP address. By configuring the ATA in DHCP mode. By configuring the ATA in PPPoE mode. Point-to-Point Protocol over Ethernet (PPPoE) defined in RFC 2516, is a means of connecting one premise to Internet Service Provider. PPPoE is a method of encapsulating data for transmission to a far point. Its advantage is that, it eliminates need for the ITSP to manage the allocation of IP address. If DHCP or PPPoE is enabled, IP address is allocated dynamically by the respective server and static IP address need not be entered. Matrix provides unique MAC address for each ATA, which is programmed at factory. User cannot change it. It can be in the range of 00.50.C2.55.B0.18 to 00.50.C2.55.B0.1F (HEX Format). The registered series of MAC address can have a maximum of 8 different MAC addresses. Hence maximum of 8-ATA units can be connected in a single LAN. The MAC address is used by ITSP to maintain the files of individual ATA in the TFTP Server. Click on WAN.

Check that SIP Account is enabled and Registration with SIP Server is successful Check that on SIP Account page, SIP1 and SIP2 are not disabled Make sure that computer s IP address is in the same subnet as ATA s IP address. Ping the ATA. Click Start Programs Accessories Command Prompt. Type ping in the command prompt followed by ATA s IP address and Enter. ATA should respond. Otherwise make sure that computer s Ethernet adaptor is ok. Make sure that Password is correctly entered. Otherwise default the system. SETU ATA2S System Manual 97

Password was changed but now it is forgotten Cannot change the Password Telephone port: No dial tone, Error tone is heard. Only Error Tone is heard when user of any phone connected at FXS1 or FXS2, goes OFF-Hook No other way, except to restore the default configuration file by resetting ATA. Ensure that retyping of new Password is correct. Error tone may be due to SIP Account not registered. Check Phone port configuration. Ensure that it is the same phone port which is assigned the SIP Account number from the ISP. Make sure the telephone is plugged in appropriate port, Phone1 or Phone2. Verify the SIP ID number, entered is correct and active/enabled. Check that, on SIP Account page, SIP1 and SIP2 are enabled and on FXS port page for OG Calls, SIP1 assigned to FXS1 and SIP2 is assigned to FXS2 =X=X= 98 SETU ATA2S System Manual

Appendix B: Applications Typical deployment of SETU ATA2S is explained for following applications: 1. Making normal VoIP calls. 2. Making calls via PBX and connecting multiple ATA. Normal VoIP calls: Today the Internet Connection from the service provider is available at most of the places. Hence, Matrix ATA can be used widely in a home or small offices, for making and receiving VoIP calls through the ITSP.

MAC Media Access Control Address - The unique address that a manufacturer assigns to each networking device. MAC is Media Access Control address in the form of 48-bit number, which is unique to the LAN NIC (network interface card). It is programmed into the card at the time of manufacture. IEEE registration authority administers MAC address scheme for all LANs which conform to IEEE, 802stds. Including both Ethernet and token ring. Consists of two parts: 24-bit company id (manufacturer ID0 and 24-bit Extension id (board id) Destination and source MAC names are contained in the header of the LAN packet and are used by various devices like hubs, bridges. A VoIP Service Provider will typically have its subscribers register with the Service Provider s VoIP service server before starting a subscriber s service. Often, an ITSP will require the registration of the MAC addresses of any devices directly connected to their network. NAT It is the Network Address Translation. Mechanism for reducing the need for globally unique IP addresses. NAT allows an organization with addresses that are not globally unique to connect to the internet by translating those addresses into globally routable address spaces, also known as Network Address Translator. 106 SETU ATA2S System Manual
