1. Introduction Welcome Thank you for choosing the New Rock Hybrid Office Telephone System, OX10. The System combines the rich feature set of legacy PBX with the advantages of easy connectivity and low cost of Internet telephony. It provides the common features of PBX systems, including auto-attendant, direct inward dialing, three-way conference calling, call transfer, call waiting, call pick up, distinctive ring, hunt group, and etc. The Systems has built-in analog phone ports and CO line ports (FXO ports) for connection to PSTN, and also has built-in SIP adaptors to provide SIP trunks to Internet Telephony Service Provides (ITSP). The Systems support also tie trunks for inter-system direct communication over IP network, forming a private telephone network crossing offices in different regions. The System is easy to install and configure. For a typical deployment, the configuration of the System by an administrator can be completed in just few minutes. A user-friend Web-based utility allows you to change the settings of the System to better meet your usage habits, to monitor the real time information and the status of the System, and also to upgrade the software of the system on a fly. Typical Application Models Below are examples of the System deployment models: 3

a) The System is installed in an office with connections to both PSTN and ITSP. In this case, the FXO ports of the System are connected to the CO lines, and the SIP trunks of the System are connected to the ITSP. The connection to PSTN allows you to keep the connectivity with the current telephone service provider and keep the phone numbers you have used. The connection to the ITSP allows you to benefit from competitive calling rates, especially for long distance calls and international calls. The built-in connections to ITSP and PSTN allows you to enjoy the benefits of PSTN failover, i.e. when the System experiencing power shortage or IP network failure, the System will redirect outbound calls to PSTN automatically. b) The Systems are installed in headquarter and offices of different locations, and they are connected each other with tie trunks over Internet or enterprise VPN to form the enterprise private telephone network. In this case, each of the System has local connection to PSTN through CO lines for incoming and outgoing calls, while they are inter-connected directly with SIP-based tie trunks for passing calls among the Systems. The advantages of the telephone network deployed like this are i. Direct inter-system calling with extension number. ii. iii. iv. Call transfer across Systems Operator sharing CO line sharing. For example, a call from the office in Shanghai to a customer in Beijing will be routed from the System in Shanghai to the System of Beijing office via the tie trunk between the two Systems, and the call will be dialed out to the customer through a an CO line on the System in Beijing. By sharing trunk resources, significant saving could be achieved. Models of OX10 OX10 includes the several models listed below. Models OX10-6S/2* Description 6 extensions, 2 CO lines, 20 SIP trunks 4

2. Getting Started When you finish with this chapter, you should be able to connect the System to the PSTN in just few minutes and start receiving and making calls. The steps below guide you to connect the System with CO lines, extensions and power supply. Place flat the System on a firm, ventilated platform. Insert the plug of power adaptor into the AC outlet, and connect another end of the adaptor to the power port ( 5 in Figure 2) of the System. The PWR light (1 in Figure 1) on indicates that the power supply of the System is normal. (Figure 1) Do not connect a CO line to a FXS port 7 for avoiding port damage. Connect the CO lines to FXO ports 8. Connect analog phones to FXS ports. Note: The corresponding extension numbers are 200, 201, 202 and 203 etc. in an increasing order. (Figure 2) 6

Now the System is ready for use. You can make external and internal calls. It is suggested that you spend few minutes for getting acquainted with the basic default configuration of the System. You can find details for factory settings and the use of features in Appendix 2 and Appendix 3. Extension numbers 200,201,202,203 Operator 200 Basic dialing rules Operator call Dial 0, or 200 Outbound call Dial 9 Call transfer (During the conversation) make a hook-flash, or press **, dial the third party s extension number, and hang up after the call is connected Call pickup Dial *50 Three way conference During two-way conversation, hook-flash and dial *79 followed by the third party number to call the third party; finally, hook-flash again to establish three-way conference 7

3. Accessing the Web-based Utility The Web-based utility allows you to perform the following operations: a) Make changes to the configurations b) Inquiry the System information, including registration, network parameters, and call status c) Manage the logs d) Upgrade the firmware To access the Web-based utility, you need to connect a PC to the System,.and you can choose one of the two ways to do it: Method 1: If the PC is on the Local Area Network (LAN), you can simply connect the System to the router. Method 2: If there is no LAN in your working environment, you may connect the PC directly to the System with a cross-over Ethernet network cable. The steps to obtain the System IP address: 1) Connect a phone to one of the FXS ports on the System 2) Pick up the phone and dial ## 3) Listen to the announcement of IP address 8

Enter the Web-based utility by filling in the IP address of the System at the IE address bar of your PC. Enter password, admin (lower case) Click Login 9

4. Connecting to the IP Network Typically, there are three connection scenarios, and the settings of them are different: - The System is connected to the LAN or Internet, and the IP address is acquired through DHCP service - The System is connected to the LAN or Internet, and the System is assigned with a static (public) IP address - The System is behind a ADSL modem, and the IP address is acquired through PPPoE By default, the System is set to automatically acquire the IP address through DHCP service. Therefore, if the System in installed as the first scenario, there is no need to change the System setting. If the System is installed as one of the other two scenarios, you need change the network settings of the System through the Web-based utility. For the second scenario: 10

Select Static Fill in the IP address assigned Click Submit For the third scenario: Select PPPoE Fill in user name and password acquired from ISP Click Submit 11

5. Registering to ITSP This section will introduce how to establish the IP Trunks between System and the platform of an ITSP. If this feature is not required in your installation, skip this section. 5.1 Preparations Before you start configuring the SIP trunks of the System, you should first collect registration information from your ITSP. The location of ITSP Platforms Information Description The address of ITSP Registrar It is either a static (public) IP address with port number, or a domain name with port number. Example: 168.33.134.50:5060, or, www.mysip.com:5060 The address of the Proxy Server Usually, it is the same as above The IP trunk Accounts Account Trunk account number1 Registration password 1 Trunk account number 2 Registration password 2 Description Registration account number Password of the account 12

5.2 Setting the IP Trunk Account Fill in the port number used by the System for SIP registration Fill in the registration server address and port number Click Submit 5.3 Adding More IP Trunks Fill in the phone number assigned to the trunk Fill in the registration password Click Add Enable the registration If there is more than one IP Trunk, repeat the above steps until you add all IP trunks. Click Submit when finished. 13

6. Making the System Working the Way You Like Click the submit button after changing configurations on each screen, and pay attention to the prompts after submit to see if configuration changes have been successfully accepted by the System. 6.1 Making Your Own Greeting on a Phone The System provides the following default greetings of auto-attendant: - For working hours: Thank you for calling. If you know your party's extension, please dial it now. Or, to transfer to an operator, press 0 - For non-working hours: Thank you for calling. The office is closed. If you know the extension, please dial it now Following the steps below you can replace the system default greetings with your own greetings: 1 Pick up a phone, and dial *81, and start to record the greeting after hearing a prompt tone, and hang up after finishing the recording 2 Pick up a phone, and dial *8200 to audit the recording 3 Repeat Step 1 and 2 until you satisfy with the recording 4 Pick up a phone and dial *8301 to save the recording for working hours, or dial *8302 to save the greeting for non-working hours 6.2 Changing the Schedules of Auto-Attendant The System provides three schedules of auto-attendants: - Business hours only: Used for offices opening 24 hours a day and 7days a week - Non-business hours only: Used for offices not in open, such as during holidays - Customize: Used for office opening on regular times. 14

Select the schedule type: Customize Set the start day (e.g. Monday) and end day (e.g. Friday) of working for each week and the start time (e.g. 8:30) and end time (e.g. 17:30) of working for each day according to the open time of your office. 6.3 Setting Multiple Operators By default, the System is configured with one operator at extension 200. You can add up to three operators (including the original one) and assign a call distribution policy for them. Select up to three extension numbers as the operators Fill in the prefix for dial operators, usually 0. Select a call distribution policy for handling incoming calls The distribution policy of incoming calls will govern how the System terminates calls to the operators. The System offers two selection policies: - Sequential: select the idle operator line in left-to-right sequence in the Operator input box when calls come in each time - Circular: select the next idle operator line starting with the one selected last time in left-to-right sequence in the Operator input box when calls come in each time. 15

6.4 Changing Extension Numbers By default, each FXS port is assigned with an extension number, started with 200. You can make your assignment. Enter the new extension number 6.5 Setting the Restriction Levels of Outbound Calling The System provides five levels of outbound restriction: - Call Barring: the extension is not allowed to make any call - Internal: the extension is allowed to make internal calls; - Local: the extension is allowed to make internal and local calls - Domestic: the extension is allowed to make internal, local and domestic long-distance calls; - International: the extension is allowed to make any call Assign the restriction level 6.6 Changing the Prefix of Selecting an Outbound Trunk By default, prefix 8 is used when selecting an IP trunk for an outbound call, and 9 is used when selecting an analog trunk. You can make change to the prefix, or you can eliminate prefix when making outbound call. 16

You might notice that when eliminating the prefix for selecting a trunk, it is hard for the System to recognize whether the number you dialed is an extension number or a PSTN number. To resolve the number confliction, when the prefix is eliminated for outbound dialing it is required to add * before the extension number when making an internal call. Here is an example of adding a dialing rule: dial 7 to select the trunk with number 51230012. Click Add Rule Fill in 7 as the prefix to select the analog trunk Select the trunk with number 51230012 6.7 Setting a Ring Group To set a ring group, you can just follow the steps below: Click Add Group Select a prefix (e.g. 1) for the group Select Group Ring as the hunting policy Fill in the numbers of the members in the group. In conjunction with this setting, it is suggested that the prefix of the group should be included in the voice menu of auto-attendant. For example, Dial 1 for emergency service. 17

6.8 Changing the Policy of Hunting Group In addition to the group ringing, the System also supports sequential and circular hunting policies. You can refer to Setting Multiple Operators for the detailed description of sequential and circular policies. Click Add Group. Select a prefix (e.g.3) for the hunt group Select Sequential or Circular. Fill in the extension numbers as the members in the group. 6.9 Allowing Call Transfer to External Terminals An operator can transfer the call to an external terminal. This feature is disabled by default. You can enable it as below. Select Allow 6.10 Taking an Analog Trunk Out of Service In case of FXO port failure or other maintenance situation, you can take the trunk out of service, i.e. the System will not accept any incoming call or make outbound call on that trunk. 18

Select Off. Likewise, an IP trunk can also be taken out of service. Select Off 6.11 Setting Incoming Only One-way Trunk Select Not Allowed Select Not Allowed 6.12 Displaying the Caller ID on Extensions You surely expect to see original caller s number when your extension is ringing. However, depending on how the call gets to your extension, you may or may not be able to see the original caller s number. The following table lists scenario of the display of caller ID. Incoming Call Direct Transfer Inward Auto Blind call Attended transfer Dialing Attendant transfer (DID) 19

Number Original Original Original The operator s shown on call s call s call s extension number extension number number number Further, to display the original caller s number on extensions, the caller ID detection function on the analog trunks should be enabled. By default, the setting is off. Please confirm with your service provider that the caller ID service has been activated for the analog trunk. Enable caller ID detection 6.13 Adjusting Voice Volume To increase voice volume level towards to the local phone: Increase the db value in Gain to Terminal To increase voice volume level towards to the external called party: 20

Decrease the db value in Gain to IP 21

7. Managing Direct Inward Dialing (DID) You may want to assign phone numbers from your ITSP to certain extensions such that when people calls these numbers the incoming calls will be terminated directly to the corresponding extensions, without being transferred by auto-attendant or operators. This feature is called Direct Inward Dialing (DID). You can activate DID function on the trunks simply by filling a corresponding extension number. Fill in the extension number 8. Building a Private Telephone Network 8.1 Typical Application Models Your company may have offices in multi-locations, such as in different buildings or in different regions. It is a cost effective deployment plan in which you install the Systems in each location and establish the communication among the Systems through your company s private IP network or through Internet. The private telephone network built with OXs provides the advantages for your telephone operation: a. Allowed to centralize operator service in one location b. Allow to make Inter-system calling crossing different locations by directly dialing the extension number of the other party c. Allow to transfer calls to extensions on different systems d. Allow to share trunk resource among systems. Note: this feature can turn an international call into a local call 22

e. You can expand the capacity of the telephone system with the growth of your company 8.2 Basic Conditions for Building a Private IP Telephone Network You should meet the following requirements when you plan the deployment: a. The Systems must be installed on the same LAN, or VPN, or on Internet with static (public) IP address b. The extension numbers on systems must be unique. Example: if the extension number of System A is 2XX, then that of System B should avoid to assigning extension numbers started with 2. 8.3 Configuring the System for Private IP Telephone Network For all networked Systems, fill in the following information Click Add to add a System to the table Fill in the IP address of the System Fill in the mapping rule of the extension numbers of the System, e.g. 2XX or 21X. If the trunks are allowed to be shared by other Systems Fill in the area code of the System, e.g. 021, if the System is installed in the office in Shanghai Fill in the phone number of the System. 23

9. Administration 9.1 The Difference between Administrator and Operator The System supports two levels of permissions: - An administrator is allowed to conduct operation on the Web-based utility without limits - An operator is mainly allowed to configure extension, analog trunk and IP trunk (Note: an operator is not allowed to change the ITSP s address). He/she is not allowed to perform most of the other operations on the Web-based utility 9.2 Changing the Password Only administrator can change administrator and operator passwords. Fill in a new password Re-enter the new password Click Submit 9.3 Restarting the System Click Restart 24

Generally, you do not need to restart the System. Most of the configuration changes will take effect after you click Submit button. Click Reboot System. When the settings of network are changed, it is required to reboot the 9.4 FAQs and Solutions # Problems Solutions 1 FXS/FXO indicators #1, 3, 5, 7 and 2, 4, 6, 8 cross flash after you power-on the system 2 Call out through IP trunk, unsuccessful second stage dialing. 3 Outbound calls from IP trunk fail. 4 Unable to pick up a specified extension. It indicates that the System has detected an IP address conflict condition. You should resolve the address confliction. DTMF setting is inconsistent with the platform, so you should change OX DTMF parameters. 1 Check if the dialing rules are set correctly. 2 Check if the IP trunk is registered normally. Check if the extension is allowed to be picked up. 25

5 Calls cannot be transferred to other extensions. Check if Call Hold for the line is activated. Appendix 1: Function List Name Auto-attendant Operator Call Distribution Queuing Description It is the internal service of the System, which provides pre-recorded voice menu and, once the caller enter the selection, transfer the call to the extension or operator accordingly. Only one level of menu is supported. Up to three extensions can be set as the operators. When the caller selects operator answer on the voice menu of auto-attendant (e. g. dial 0), the call will be transferred to the operator. When there are more than two extensions used for the operators, the System will follow the call distribution policy to terminate the incoming calls. Two extension selection methods are supported: Sequential and Circular. If the extensions for the operators are all busy when a call is coming in, the System will put the call into the queuing list (the caller will hear music), and calls in the list will be processed based on the first in first out rule. Greeting Management File You can replace the System default greetings (voice files) with your own files. You are allowed to 1 Make recording of your greeting files on a phone, or 2 Upload the pre-prepared voice files from your PC. Note: The uploaded greeting files must be in G.711 and/or G.729 codec. The Length of Extension Number 1-5 digits. 26

Disabling Extension Direct Inward Dialing (DID) Hunt Group Group Ringing Three-way Conference Call Do Not Disturb Call Splitting Blind Call Transfer You can disable an extension, and in this status, the extension is no longer able to receive or make calls. An external call will be directed to the extension without going through auto-attendant. When a call is made from this extension to PSTN, the System will select the designated trunk and the DID number will be presented to the called party. A group of extensions can be called with dialing the prefix or can be selected by pressing the prefix number on the voice menu of the auto-attendant. The System will terminate the call to one or multiple extensions in the group, following the policies for hunting. Hunting policies supported by the System are Sequential, Circular, and Group Ringing. The System will ring idle extensions of the group simultaneously when incoming calls are redirected to the group. The controller of the conference can invite up to two parties (not including he/her self) to the meeting, by making calls to the other parties. The controller can end the conference by hanging up the phone. The external caller will hear a busy tone when dialing the extension which is set to Do Not Disturb When terminating an incoming call to the extension with this feature set, the System will not own ring the extension but also ring at the same time the pre-entered phone number, such as a mobile number or another extension. Transfer a call to another extension without any intervention. Attended Transfer Call The other party in talk will be put on hold, and a call is made to the third party. A conversation can be taken 27

place privately before the caller on hold is connected to the third party Call Transfer to External Destination Call Forwarding Call Waiting Call Pickup Toll Restriction A call either from internal or external, can be transferred manually to a phone through CO lines or SIP trunks If an extension is in certain conditions, any call to it will be redirected to the pre-configured destination number. There are three conditions associated with CF: 1 Redirect calls to the new destination regardless the status of the extension 2 Redirect calls to the new destination when the extension is busy 3 Redirect calls to the new destination when there is no answer to the ring (for example after three rounds of ring). The System will alert by faint beep the person in talk when there is a new call to the extension. The person can take the new call and put the party of the first call on music. Allow you take the call from your extension that is ringing on another extension. If this is a call to operator, you can simply pick it up by dialing the function code. If this is a call to non-operator extension, you can pick it up by dialing the function code followed by the number of the extension. The System can assign one of the five toll restriction level to each extension: Level 1: Prohibit not allowed to make any external call Level 2: Internal only allowed to make internal call Level 3: Local only allowed to make internal and local call Level 4: Domestic only allowed to make internal, local and domestic call 28

Level 5: International in addition to calls mentioned above, international call is also allowed Hotline Speed Dials CRBT Caller ID Display PSTN Failover Digit Map Function Codes Allow you to dial a pre-programmed external number in an abbreviated way. The System supports two modes: 1 Delayed 2 Immediate Permit fast dialing of frequently used numbers. Lists of 30 numbers are allowed to be programmed by users. For example, you can set speed dialing number 20 for one of your customer. When you make a call to the customer, you simply dial **20. Users are allowed to select the music as ring back tone. Display the caller s number on the extension. When the System experiences power-off or not being able to register to the ITSP s server, the System will route the outbound calls to PSTN through analog trunks. A table of streams that is used to define the dialing plan. A carefully designed Digit Map allows the System to successfully identify the end of dialing digits.
