3 Introduction This document provides customers using Quintum Tenors the necessary information (as an example) to configure their Tenors to originate or terminate calls to/from a Cisco VoIP Gateway without the use of external Gatekeeper registration. This document includes sample applications along with sample configurations for the Tenor. Where possible, we will also provide sample Cisco Dial Peers. Quintum, however, cannot be responsible for configuring any Cisco equipment directly and can only provide this information based on our current customers who are using Cisco. This document is intended to be used by those technicians that have experience with both Cisco and Quintum. This document pertains to both 1G and Tenors. First Generation Tenor (or 1G Tenor) refers to Tenor A400, A800, D800, D1800, D2400, and D3000. Second Generation Tenor (or Tenor) refers to Tenor CMS, as well as Tenor AS, AX, BX, and DX. The information provided here is only an example. Your application requirements may be different, but you should be able to use this as a guideline. Additionally, while some of this description provides information on the line configurations (such as signaling and type, etc.), the main focus is to provide the necessary information to route calls to/from a Cisco. The connection after that may vary. Finally, this document will provide 2 examples. The first is Cisco terminating VoIP to a Tenor, and the second is a Tenor terminating VoIP to a Cisco. Required Information Before setting up this application, or any other, there is always information that you should gather so that you can be prepared and understand how you will need to configure your Tenor, and your Cisco. For analog and digital Tenors, Quintum has a site survey form that you may find useful (check our web site for these forms); otherwise, the following information should be identified at a minimum: IP address of all devices (Tenors & Cisco, etc.) Audio codec/compression to be used Dial/number patterns to be sent over IP Dial/number patterns to be dialed out to PSTN Disconnect supervision and answer supervision requirements Digital line information (physical configuration and signaling requirements) Page 3 of 27

4 Cisco Terminating VoIP to Tenor(s) (Cisco > VoIP > Tenor) Application Description Figure 1 As shown in Figure 1 above, this application has a Cisco Gateway in New York (there could be more there) and 3 Tenors in different countries. This mix will help to provide additional examples for future reference. 1G: There are 2 analog A400s (Romania & Egypt) and one D2400 (Portugal). : There are 2 Tenor AXs (Romania & Egypt) and one Tenor DX (Portugal). Each Tenor is connected to the local phone company using either analog lines (Analog sites) or a T1 using ISDN signaling (Digital site). The call flow is as follows: Calls from the Provider switch in New York are sent to the Cisco, and the Cisco routes the call, using its dial peers, using the number pattern of countrycode+number. At each termination country, the Tenor makes sure that the correct digits are dialed out to the local phone company. The Cisco must be configured never to allow more calls to any one site than that site can handle at one time (for example, send only 4 calls at a time to the A400s). An audio codec of G.729 is used for this network and answer supervision is provided by the Tenors at the termination side. Finally, for VoIP security, the Tenors are configured with IP allow tables so that only those IP addresses configured are allowed to make VoIP calls through the Tenor. 1 Sending the international prefix, or any non-e164 digit/character, is a violation of the H.323 specification. The Tenor can address this in most cases. See the Appendix for more information on the E.164 format as it relates to H.323. Page 4 of 27

5 Tenor Configuration and Notes The following configuration information takes into consideration that the Tenor is at factory default with no previous configuration loaded. Only the IP address, subnet mask, and default gateway are configured. All configuration is done from the Command Line Interface (CLI). Not all configuration items are shown; only those items necessary to this application. Additionally, if a command is shown without any parameter, this means that you should enter the command only, so that any pre-configured setting is deleted. For example, if you enter the command areacode without any parameters, it will delete the set area code. Finally, the following configurations are laid out so that an engineer/technician that has experience with configuring Tenors will be able to understand this. If you have no experience with configuring Tenors from the Command Line Interface, we suggest you contact the QTAC for support. Site A Romania (Analog Tenor) Site A has 4 analog lines connected from the local PSTN to its PSTN interface, and uses both our answer supervision software and forward disconnect (battery removal) for disconnect supervision. This site terminates all calls to the 40 country code with a city code of 232.

Sets the channel hunting to Ascending Round-Robin. This is useful on analog so that the calls will hunt in a round-robin fashion. This way, if there is one line that is failing, it will only be attempted 1 out of 4 times (or 8 if this were an A800). See the CLI guide on this command for more information. This sets the first lampattern (hop-off) to match on In this case, no replacement is necessary. When a call comes in to this unit where the digits match this pattern, the matching digits of the incoming call are deleted from the number and the remaining digits are sent to the PSTN lines. For example, if were sent to this Tenor, it would match the pattern of and the matching digits would be deleted. Only would be dialed to the PSTN. Only characters 0 through 9, *, # are valid. This sets the signaling to Loop Start with Forward Disconnect. The Forward Disconnect is disconnect supervision based on battery removal. The local PSTN must support this type of disconnect supervision and use it when the far end hangs up the phone. When this is done, the PSTN removes the battery from this line and the Tenor disconnects the call. Check with your PSTN provider on this. This enables software-based answer supervision in thetenor. This sets milliseconds (45 seconds) as the time the Tenor waits to use the software-based answer supervision. If the Tenor fails to detect voice after this time has run out, the Tenor considers the call connected. NOTE: If the unit was at factory default, then all channels should be enabled already and there is no need to change the channels. 1G config gkadmin# allow 1 Quintum# epad 1 Moves to the first allow group for VoIP restrictions based on IP.

Only characters 0 through 9, *, # are valid. 1G config pstntg lamrep 1 0 The lamrep will add digits to the number after the lampat digits are deleted off.

This sets the signaling to Loop Start. This is standard signaling for analog lines with no form of supervision (answer or disconnect) set for this signaling. This will enable software-based answer supervision in the Tenor as well as disconnect tone detection from the PSTN. The disconnect tone detection is used when the PSTN will send a tone to the Tenor to indicate that the far end has disconnected the call. When set correctly, the Tenor will be able to detect this and disconnect the line upon receiving the tones. This will set milliseconds (45 seconds) the time the Tenor will wait to use the software based answer supervision. If the Tenor fails to detect voice after this time has run out, the Tenor will consider the call connected. NOTE: If the unit was at factory default, then all channels should be enabled already and there is no need to change the channels. 1G config gkadmin# allow 1 Quintum# epad 1 1G config gkadmin allow ip EndPointAddress Directory- add at 1 1G config gkadmin allow mask EndPointAddress Directory- change 1 mask G config gkadmin allow 2# ip EndPointAddress Directory-2# add at 1 1G config gkadmin allow 2# mask Moves to the first allow group for VoIP restrictions based on IP.

For example, if were sent to this Tenor, it would match the pattern of and the matching digits would be deleted. So only would remain of the number dialed. Since there is no lamrep, then would be dialed to the PSTN. Only characters 0 through 9, *, # are valid. This sets the PSTN trunkgroup to use CCS (ISDN) for signaling.

Since this country requires A-Law, you must set this Tenor for A- law. Additionally, even though we are not using the PBX interface, the law must be configured the same in both the PBX and PSTN interface or there will be problems. Sets the line of the PBX interface to E1. Sets the E1 line code to HDB3. Page 11 of 27

Since this country requires A-Law, you must set this Tenor for A-law. As indicated above, the law for both line 1 1 and line 1 2 must be the same or you will experience poor voice quality. Sets the line of the PSTNinterface to an E1. Sets the E1 line code to HDB3. You will need to check with your PSTN provider to verify this setting. Sets the CRC for the E1 to No. Again, this is a setting that you need to verify with your PSTN provider for this line. Enables ISDN signaling group 2 with a name of PSTN_ISDN_01 Sets the ISDN signaling type to ETSI. Check with your PSTN provider to verify this setting. Sets the orientation of the ISDN on the Tenor to User side. This is typically correct when connected to the PSTN as the PSTN will be network side. If you are connecting to a switch at your location, you may need to check with your switch settings for this as the Tenor should be set opposite of what it is connecting to. Sets the D-channel (ISDN signaling channel) to channel 16 on the E1. E1s always use channel 16 for the D- channel while T1 s use channel 24 when set for ISDN. Sets the unit id to 1. Anywhere in the Tenor where you see unit, it will always be 1. 1G config signaling 2# fasline 2 Sets the ISDN line to line 2 (PSTN). Page 12 of 27

Sets the 2 nd allow group to allow the IP address of the Cisco to send calls to this unit. Sets the subnet to so that only the IP address of that one Cisco is allowed. If there are more than one Cisco on the same network, you could change the mask to Sets the border element to the Tenor s IP address. Sets the voice audio codec/compression to G.729 Submits changes NOTE: Since the law was changed from U-law to A-law, you will need to reset the Tenor AFTER you have submitted the changes.

14 Cisco Dial Peer Examples The following dial peer examples are based on information from existing Quintum customers who are using Cisco to originate traffic to Tenors as the above examples show. Quintum cannot configure a customer s Cisco equipment and we can not guarantee that the dial peers listed below will work in all occasions. As always, you should verify these settings with Cisco. Dial Peer to Site A Romania The following sample dial peer will allow any calls that begin with digits to be sent to with a codec of G.729. dial-peer voice 300 voip destination-pattern session target ipv4: codec g729r8 bytes 30 Dial Peer to Site B Egypt The following sample dial peer will allow any calls that begin with any number of digits, to be sent to with a codec of G.729 dial-peer voice 301 voip destination-pattern 01120T session target ipv4: codec g729r8 bytes 30 Dial Peer to Site C Portugal The following sample dial peer will allow any calls that begin with any digits to be sent to with a codec of G.729. dial-peer voice 300 voip destination-pattern T. session target ipv4: codec g729r8 bytes 30 Cisco GW > Tenor GW Summary Using the configuration above as an example, you should find it relatively easy to configure the Tenor to receive a call from a Cisco and terminate it to the local PSTN lines.

15 Tenor Terminating Calls to Cisco Gateway Application Description Figure 2 As shown in Figure 2 above, this application will have a Cisco Gateway in New York that will receive traffic from IP (from Tenors) in Morocco and Taiwan. 1G: The Tenor in Morocco is a digital Tenor with an E1 connection (ISDN) and the Tenor in Taiwan is an A400 with 4 lines from the local PSTN. : The Tenor in Morocco is a Tenor DX with an E1 connection (ISDN) and the Tenor in Taiwan is a Tenor AX with 4 lines from the local PSTN. In Morocco, calls will come in to the Digital Tenor with the digits of 001xxxxxxxxxx 2 and we will pass these digits over IP to the Cisco (001xxxxxxx). For Taiwan, we will use 2 nd dialtone and simple Pincode verification to allow incoming calls from the PSTN to get a dial tone and then dial 1xxxxxxxxxx. The Tenor will then need to add 00 to the front of the number to send the call to the Cisco. An audio codec of G.729 will be used for this application. The Tenors will be configured not to accept any calls from IP for this application. Unfortunately, Quintum does not have a sample Cisco dial peer to address this application. Please contact Cisco to get the correct parameters on this. 2 Sending the international prefix, or any non-e164 digit/character, is a violation of the H.323 specification. The Tenor can address this in most cases. See Appendix for more information on the E.164 format as it relates to H.323. Page 15 of 27

16 Tenor Configuration and Notes The following configuration information takes into consideration that the Tenor is at factory default with no previous configuration loaded. Only the IP address, subnet mask and default gateway are configured. All configuration will be done from the Command Line Interface (CLI). Not all configuration items are shown. Only those necessary to this application will be shown. Additionally, if a command is shown with out any parameter, this means to enter the command only so that any pre-configured setting will be deleted. For example, entering the command areacode without any parameters will delete the set area code. Finally, the following configurations are laid out so that an engineer/technician that has experience with configuring Tenors will be able to understand this. If you have no experience with configuring Tenors from the Command Line Interface, we suggest you contact the QTAC for support. Site A Morocco (Digital Tenor) Site A will have an E1 line connected from the local PSTN to its PSTN interface set as ISDN/PRI (ETSI signaling). Answer and disconnect supervision on part of ISDN signaling and nothing specific need be done for this. This site will receive calls from this E1 line that will have the digits 001xxxxxxxxxx and these calls will need to be forwarded to the Cisco in New York with the 001 digits.

Enables ISDN signaling group 2 with a name of PSTN_ISDN_01 Sets the ISDN signaling type to ETSI. Check with your PSTN provider to verify this setting. Sets the orientation of the ISDN on the Tenor to User side. This is typically correct when connected to the PSTN as the PSTN will be network side. If you are connecting to a switch at your location, you may need to check with your switch settings for this as the Tenor should be set opposite of what it is connecting to. Sets the D-channel (ISDN signaling channel) to channel 16 on the E1. E1s always use channel 16 for the D-channel while T1 s use channel 24 when set for ISDN. Sets the unit id to 1. Anywhere in the Tenor where you see unit, it will always be 1. Sets the ISDN line to line 2 (PSTN). This allows this signaling group to be associated with the PSTN interface. NOTE: You may need to go back to the pstntg and enable all the channels now, since changing from T1 to E1 may not add the additional 6 channels. The command to do this is ena 1 a. 1G config gksys# border GateKeeperParam- set pbeipa G config dsp# voice 68 VoiceCodec- set cvc 68 Sets the border element to the Tenor s IP address.

Sets the route name to NY_Cisco Sets the static route destination to the IP address of the Cisco. Sets the 1 st dn pattern to send any call that begins with 001, that is a public number (1 st 0) set as a local dn (2 nd 0) and has a routing priority of 2. Quintum recommends that when building sroutes to non-tenor equipment, that you set the number type to LDN as this will be the simplest way to route calls. If this route was to another Tenor, then you could pick whether it is an LDN or LAM. The priority is normally set to 2 for LDNs and 1 for LAMs (1 being a lower priority). The priority will help in providing routes where the number pattern is the same, but you want all calls to go to one destination before going to the next. This sets the type of route to a Gateway Destination. If you wanted to have a route between 2 Gatekeepers, then you would set this to 1 for LRQ route between Gatekeepers. Submits changes. NOTE: Since the law was changed from U-law to A-law, you will need to reset the Tenor AFTER you have submitted the changes. Page 19 of 27

20 Site B Taiwan (Analog Tenor) Site B will have 4 analog lines connected from the local PSTN to its PSTN interface. Calls will come in to the Tenor from the PSTN, get a beep tone to enter a 8 digit pin that must begin with 8345 and then receive 2 nd dialtone and then dial 1xxxxxxxxxx. The Tenor will then add 00 to the front of the number and send 001xxxxxxxxxx to the Cisco in NY.

Deletes the international prefix in index 1. Sets the maximum digit length to 20 digits. Sets passthru to No so that incoming calls will be routed over IP. If this was set to 1 (for Yes), then all incoming calls would be unconditionally routed to the PBX trunk group. Will disable the modem bypass setting. Sets the channel hunting to Ascending Round-Robin. This is useful on analog so that the calls will hunt in a round-robin fashion. This way if there is one line that is failing, it will only be attempted 1 out of 4 times (or 8 if this were an A800). See the CLI guide on this command for more information. Sets the call direction to incoming only on this trunk group. It will not allow any outgoing calls. Page 20 of 27

This sets the pincode for the 2 nd dialtone to any 8 digit number beginning with When a user dials in to the PSTN interface, they will hear a beep tone. When they here this they must enter the correct pin code. If they enter a wrong pincode, they will hear a busy signal and get disconnected. This sets the signaling to Loop Start with forward disconnect. With this setting, the Tenor will recognize the removal of battery that is sent by the PSTN to indicate that the call is disconnected. The PSTN must support this type of disconnect supervision. NOTE: If the unit was at factory default, then all channels should be enabled already and there is no need to change the channels. 1G config gksys# border GateKeeperParam- set pbeipa G config dsp# voice 68 VoiceCodec- set cvc 68 1G config iptg# outpref 00 IPDialPlan- set outp 00 1G config be sroute StaticRoute- 1G config be sroute StaticRoute- route NY_Cisco set name NY_Cisco callsig set csip Sets the border element to the Tenor s IP address.

23 Summary The above applications/configuration do provide some standard examples to be able to originate and terminate calls to/from Cisco when using a Quintum Tenor. There are many other ways that this could be done, but this will provide you information to get you started.

24 Appendix Extract of Appendix V of the ITU-T H.323 Version 4 Draft (11/2000) Use of E.164 and ISO/IEC Numbering Plans V.1 E.164 Numbering plan ITU-T Recommendation defines E.164 numbers the following way for geographic areas: Figure V.1/H International public telecommunication number structure for geographic areas Similar descriptions are also defined for non-geographic areas. Recommendation E.164 further defines country codes (CC) for all the countries and regions of the world. An international E.164 number always starts with a country code and its total length is always 15 digits or less. More importantly, it does not include any prefixes that are part of a dialing plan (for example, 011 for an international call placed in North America, or 1 for a long-distance call), nor does it include # or *. The number is a n E.164 number with CC=49 for Germany. A national number is the international number stripped of the country code, in this case. The subscriber number is the national number stripped of the national destination code, in this case. An E.164 number has global significance: E.164 number can be reached from any location in the world. A dialed digit sequence, however, only has significance within a specific domain. Within a typical private numbering plan in an enterprise, for example, a prefix, such as 9, may indicate that a call goes outside, at which point the local telephone company s dialing plan takes over. Each telephone company or private network is free to choose its own dialing plan. It is also free to change it as it pleases an frequently does so (adding new area codes, for example). In a typical geographically determined network where user input telephone numbers manually and where user do not travel too much, having different dialing plans everywhere is usually a problem. However, when a user travels, the user must determine the other network s numbering plan in order to place calls. When computer systems perform the dialing automatically, the user is usually required to customize the dialing software for every region or network. Because of these issues with varying dialing plans and automated dialing, it is essential to be able to refer to an absolute telephone number instead of what you have to dial to reach it from a specific location. Proper usage of E.164 numbers can resolve these issues. Many systems use E.164 numbers instead of dialed digits: for example, a PBX may gather the dialed digits from a Page 24 of 27

25 user on a telephone and then initiate a call to the local phone company using an E.164 number in the Called Party Number information element in Q.931. When completing the Called Party Number IE< specifying the numbering plan as ISDN/telephony numbering plan (Recommendation E.164) indicates an E.164 number. Specifying the type of number as unknown and specifying the numbering plan as unknown indicates dialed digits. The following are a set of definitions from E.164. Number A string of decimal digits that uniquely indicates the public network termination point. The number contains the information necessary to route the call to this termination point. A number can be in a format determined nationally or in an international format. The international format is known as the International Public Telecommunication Number which includes the country code and subsequent digits, but no the international prefix. Numbering plan A numbering plan specifies the format and structure of the numbers used within that plan. It typically consists of decimal digits segmented into groups in order to identify specific elements used for identification, routing and charging capabilities, e.g. within E.164 to identify countries, national destinations, and subscribers. A numbering plan does not include prefixes, suffixes, and additional information required to complete a call. The national numbering plan is the national implementation of the E.164 numbering plan. Dialing plan A string or combination of decimal digits, symbols, and additional information that define the method by which the numbering plan is used. A dialing plan includes the use of prefixes, suffixes, and additional information, supplemental to the numbering plan, required to complete the call. Address Prefix A string or combination of decimal digits, symbols, and additional information which identifies the specific termination point(s) of a connection in a public network(s) or, where applicable, in interconnected private network(s). A prefix is an indicator consisting of one or more digits, that allows the selection of different types of number formats, networks and/or service. International prefix A digit or combination of digits used to indicate that the number following is an International Public Telecommunication Number. Country code (CC) for geographic areas The combination of one, two or three digits identifying a specific country, countries in an integrated number plan, or a specific geographic area. Page 25 of 27

26 National (significant) number [N(S)N] That portion of the number that follows the country code for geographic areas. The national (significant) number consists of the National Destination Code (NDC) followed by the Subscriber Number (SN). The function and format of the N(S)N is nationally determined. National destination code (NDC) A nationally optional code field, within the E.164 numbering plan, which combined with the Subscriber s Number (SN) will constitute the national (significant) number of the international public telecommunication number for geographic areas. The NDC will have a network and/or trunk code selection function. The NDC can be a decimal digit or a combination of decimal digits (not including any prefix) identifying a numbering area within a country (or group of countries included in one integrated numbering plan or a specific geographic area) and/or network/services. National (trunk) prefix A digit or combination of digits used by a calling subscriber, making a call to a subscriber in his own country but outside his own numbering area. It provides access to the automatic outgoing trunk equipment. Subscriber number (SN) The number identifying a subscriber in a network or numbering area. V.2 Private Network Number Private Network Numbers are used in a private or virtual private telephony networks, e.g., a corporate network of PBXs and virtual private lines. ISO/IEC defines Private Network Number (PNP) as having up to three regional levels. A PNP number shall comprise a sequence of x decimal digits (0,1,2,3,4,5,6,7,8,9) with the possibility that different PNP numbers within the same PNP can have different values of x. Then maximum value of x shall be the same as for the public ISDN numbering plan, see ITU-T Recommendation E.164. Level 2 Regional Number Level 1 Regional Number Level 0 Regional Number Figure V.2/H.323 Structure of a PNP number with three levels of regions A level n Regional Number (RN) shall have significance only within the level n region to which it applies. When that number is used outside that level n region, it shall be in the form of an RN of level greater than n. Only a Complete Number shall have significance throughout the entire PNP. A typical example in North America would be a 4-digit extension as the Level 0 Regional Number: a 3-digit location code combined with the 4 digit extension would form the Level 1 Regional Number. The Level 2 Regional Number would be nil. A prefix could also be used to signal which regional number is used, and would not be part of the regional number per se, but only part of the dialing plan. Again, a typical example would be the Page 26 of 27

27 use of digit 6 to access a Level 1 Regional Number, and no digit for a Level 0 Regional Number. The following are a set of definitions from ISO/IEC 11571: Private Numbering Plan (PNP) The numbering plan explicitly relating to a particular private numbering domain, defined by the PISN Administrator of that domain. Region The entire domain or a sub-domain of a PNP. A region does not necessarily correspond to a geographical area of PISN. Regional Number (RN) A particular form of a PNP Number which is unambiguous in the region concerned. Complete Number A number which is unambiguous in the entire PNP, i.e. which corresponds to the highest regional level employed in that PISN. V.3 H.323 version 1, 2 and 3 usage H.323 version 1, 2 and 3 systems had a terminology problem with respect to dialed digits and real E.164 numbers. References to E.164 addresses in those version actually referred to dialed digits and not E.164 digits, as the names of the fields implied. In H.323 versions 2 and 3 systems, a real E.164 number was placed in the publicnumber field and not in the e164 field. The e164 field thus corresponded to a dialed digits sequence. Beginning with H.323 Version 4 systems, the field e164 was renamed to dialeddigits and the field publicnumber was renamed to e164number. The name change was intended to more explicitly convey that dialed digits shall be stored in the dialeddigits field and the E.164 numbers shall be stored in the e164number field. Page 27 of 27
