Introduction These Application Notes describe the configuration procedures required for the AudioCodes MP-124 Analog VoIP gateway to successfully interoperate with Avaya SIP Enablement Services and Avaya Communication Manager via a SIP interface. The AudioCodes MP-124 gateway provides voice technology to connect analog telephones, fax machines and modems to the SIP servers and IP based PBX systems. In the reference test network simulating a hosted telephony solution, this technology enabled the audio endpoints behind the AudioCodes MP-124 at the customer enterprise sites to register with Avaya SIP Enablement Services server at the service provider data center, effectively making them SIP endpoints. These analog endpoints were then able to utilize the telephony features of Avaya Communication Manager. The MP-124 gateway incorporates up to 24 analog ports for connection to telephones, fax machines and modems, supporting up to 24 simultaneous VoIP calls. 1.1. Reference Test Network Figure 1 shows the reference configuration used for simulating a hosted telephony solution with two customer enterprise sites and a service provider data center. The service provider data center site consists of an Avaya SIP Enablement Services (SES) server, an Avaya S8500 Media Server running Avaya Communication Manager and an Avaya G650 Media Gateway. The access to the PSTN for all the enterprise customers was provided by an ISDN PRI trunk from an Avaya G650 Media Gateway to the PSTN. Each enterprise site consists of an AudioCodes MP-124 analog VoIP gateway, with the analog ports connected to the analog telephones, a fax machine and a modem. The AudioCodes MP-124 is connected to the service provider data center network over an IP network via an Avaya C363T switch. Avaya 4600 Series H.323 IP telephones were also located at the enterprise sites to verify calls to and from the analog endpoints behind MP-124 gateway. Avaya 4600 Series H.323 IP telephones registered directly with Avaya Communication Manager.

Equipment and Software Validated The following equipment and software/firmware were used for the test configuration provided. Equipment Software/Firmware Avaya S8500 Media Server Avaya Communication Manager 3.1.2 (R013x.01.0.632.1) Avaya G650Media Gateway (Media Gateway Processor) 25.23.0 Avaya SES 3.1 (3.1.0.0-018.0) Avaya 4600 Series IP (H.323) Telephones 2.3 (4620SW) Analog Telephones - Avaya 363T Switch 4.5.14 AudioCodes MP-124 analog VoIP gateway 4.80A.018.007 Fax machine - PCs with modem Windows 2000 3. Configure Avaya Communication Manager This section describes the necessary configuration on Avaya Communication Manager to interoperate with the SIP interface of the Avaya SES. The following configuration of Avaya Communication Manager was performed using the System Access Terminal (SAT). After completion of the configuration in this section, perform a save translation command to make the changes permanent. 3.1. Configure SIP Trunking This section describes the steps for configuring a SIP trunk group between Avaya Communication Manager and Avaya SES. Avaya SES acts as a SIP proxy for the service provider data center in Figure 1. Thus, the AudioCodes MP-124 analog SIP gateway will direct all SIP traffic bound for the service provider data center to the Avaya SES located there. Avaya SES will then forward the inbound SIP traffic to Avaya Communication Manager. The path is the same in the reverse direction with SIP signaling flowing from Avaya Communication Manager to Avaya SES to the AudioCodes MP-124. As a result, the SIP trunk group configured in this section carries all the SIP signaling and associated media streams bound to the service provider data center from the AudioCodes MP-124 gateways at the customer enterprise sites and vice versa. These steps were performed at the service provider data center in the configuration shown in Figure 1.

Use the display system-parameters customer-options command to verify that sufficient SIP trunk capacity exists. On Page 2, verify that the number of SIP trunks supported by the system is sufficient for the number of SIP trunks needed. Each SIP call between two SIP endpoints (whether internal or external) requires two SIP trunks for the duration of the call. Thus, a call between two analog telephones behind the AudioCodes MP-124 VoIP gateway will use two SIP trunks. A call between an analog telephone behind the AudioCodes MP-124 and a non-SIP service provider (e.g., PSTN trunk) will only use one SIP trunk. The license file installed on the system controls the maximum permitted. If a required feature is not enabled or there is insufficient capacity, contact an authorized Avaya sales representative to make the appropriate changes. display system-parameters customer-options Page 2 of 10 OPTIONAL FEATURES IP PORT CAPACITIES USED Maximum Administered H.323 Trunks: 800 0 Maximum Concurrently Registered IP Stations: 2400 4 Maximum Administered Remote Office Trunks: 0 0 Maximum Concurrently Registered Remote Office Stations: 0 0 Maximum Concurrently Registered IP eCons: 0 0 Max Concur Registered Unauthenticated H.323 Stations: 0 0 Maximum Video Capable H.323 Stations: 0 0 Maximum Video Capable IP Softphones: 0 0 Maximum Administered SIP Trunks: 800 200 Maximum Number of DS1 Boards with Echo Cancellation: 0 0 Maximum TN2501 VAL Boards: 1 0 Maximum G250/G350/G700 VAL Sources: 0 0 Maximum TN2602 Boards with 80 VoIP Channels: 0 0 Maximum TN2602 Boards with 320 VoIP Channels: 0 0 Maximum Number of Expanded Meet-me Conference Ports: 0 0 (NOTE: You must logoff & login to effect the permission changes.)

Use the change node-name ip command to assign the node name and IP address for Avaya SES at the service provider data center. In this case, ses and 192.168.10.50 are being used, respectively. The node name ses will be used throughout the other configuration forms of Avaya Communication Manager. In this example, CLAN and 192.168.10.43 are the name and IP address assigned to the CLAN IP interface on Avaya G650 Media Gateway. change node-names ip Page 1 of 1 IP NODE NAMES Name IP Address Name IP Address CLAN 192.168.10 .43 . . .

  7. 7. BS; Reviewed: SPOC 9/20/2006 Solution & Interoperability Test Lab Application Notes ©2006 Avaya Inc. All rights reserved. 7 of 44 AudioCodes-SIP.doc Step Description 3. Use the change ip-network-region n command, where n is the number of the region to be changed, to define the connectivity settings for all VoIP resources and IP endpoints within the IP region. Select an IP network region that will contain the Avaya SES server. The association between this IP Network Region and the Avaya SES server will be done on the Signaling Group form as shown in Step 5. In the case of the tested configuration, the same IP network region that contains the Avaya S8500 Media Server was selected to contain the Avaya SES server. By default, the Media Server is in IP Network Region 1. On the IP Network Region form: The Authoritative Domain field is configured to match the domain name configured on Avaya SES. In this configuration, the domain name is test.com. This name will appear in the “From” header of SIP messages originating from this IP region. By default, IP-IP Direct Audio (shuffling) is enabled to allow audio traffic to be sent directly between IP endpoints without using media resources in the Avaya G650 Media Gateway. This is true for both intra-region and inter-region IP-IP Direct Audio. Shuffling can be further restricted at the trunk level on the Signaling Group form. The Codec Set is set to the number of the IP codec set to be used for calls within this IP network region. In this configuration, this codec set will apply to all calls to and from the AudioCodes MP-124 as well as any IP phone (H.323 or SIP) within the enterprise. If different IP network regions are used for the Avaya S8500 Media Server and the Avaya SES server, then Page 3 of each IP Network Region form must be used to specify the codec set for inter-region communications. The default values can be used for all other fields. change ip-network-region 1 Page 1 of 19 IP NETWORK REGION Region: 1 Location: Authoritative Domain: test.com Name: CM MEDIA PARAMETERS Intra-region IP-IP Direct Audio: yes Codec Set: 1 Inter-region IP-IP Direct Audio: yes UDP Port Min: 2048 IP Audio Hairpinning? n UDP Port Max: 65531 DIFFSERV/TOS PARAMETERS RTCP Reporting Enabled? y Call Control PHB Value: 46 RTCP MONITOR SERVER PARAMETERS Audio PHB Value: 46 Use Default Server Parameters? y Video PHB Value: 26 802.1P/Q PARAMETERS Call Control 802.1p Priority: 6 Audio 802.1p Priority: 6 Video 802.1p Priority: 5 AUDIO RESOURCE RESERVATION PARAMETERS H.323 IP ENDPOINTS RSVP Enabled? n H.323 Link Bounce Recovery? y Idle Traffic Interval (sec): 20 Keep-Alive Interval (sec): 5 Keep-Alive Count: 5

Use the change ip-codec-set n command, where n is the codec set value specified in Step 3, to enter the supported audio codecs for calls routed to Avaya SES and the AudioCodes MP-124. Multiple codecs can be listed in priority order to allow the codec to be negotiated during call establishment. The list should include the codecs the enterprise wishes to support within the normal trade-off of bandwidth versus voice quality. It must also include the preferred codec configured on the AudioCodes MP- 124. The example below shows the values used in the tested configuration. change ip-codec-set 1 Page 1 of 2 IP Codec Set Codec Set: 1 Audio Silence Frames Packet Codec Suppression Per Pkt Size(ms) 1: G.711MU n 2 20 2: G.729AB n 2 20 3: 4: Page forward to Page 2.

  9. 9. BS; Reviewed: SPOC 9/20/2006 Solution & Interoperability Test Lab Application Notes ©2006 Avaya Inc. All rights reserved. 9 of 44 AudioCodes-SIP.doc Step Description 5. Use the add signaling group n command, where n is the number of an unused signaling group, to create the SIP signaling group as follows: Set the Group Type field to sip. The Transport Method field will default to tls (Transport Layer Security). TLS is the only link protocol that is supported for communication between Avaya SES and Avaya Communication Manager. Specify the node name CLAN on Avaya S8500 Media Server and the node name ses for Avaya SES Server as the two ends of the signaling group in the Near-end Node Name and the Far-end Node Name fields, respectively. These field values are taken from the IP Node Names form shown in Step 2. In alternative configurations, which do not use a CLAN board, the near (local) end of the SIP signaling group will be the procr instead of the CLAN board. Ensure that the recommended TLS port value of 5061 is configured in the Near-end Listen Port and the Far-end Listen Port fields. In the Far-end Network Region field, enter the IP Network Region value assigned in the IP Network Region form in Step 3. This defines which IP network region contains the Avaya SES server. If the Far-end Network Region field is different from the near-end network region, the preferred codec will be selected from the IP codec set assigned for the inter-region connectivity for the pair of network regions. Enter the domain name of Avaya SES in the Far-end Domain field. In this configuration, the domain name is test.com as configured in Step 3. This domain is specified in the Uniform Resource Identifier (URI) of the SIP “To” header in the INVITE message. The Direct IP-IP Audio Connections field is set to y to enable the direct audio path (shuffling) between the two IP endpoints. The DTMF over IP field must be set to the default value of rtp-payload for a SIP trunk. This value enables Avaya Communication Manager to send DTMF transmissions using RFC 2833. The default values for the other fields may be used. change signaling-group 1 Page 1 of 1 SIGNALING GROUP Group Number: 1 Group Type: sip Transport Method: tls Near-end Node Name: CLAN Far-end Node Name: ses Near-end Listen Port: 5061 Far-end Listen Port: 5061 Far-end Network Region: 1 Far-end Domain: test.com Bypass If IP Threshold Exceeded? y DTMF over IP: rtp-payload Direct IP-IP Audio Connections? y IP Audio Hairpinning? y

Add a SIP trunk group by using the add trunk-group n command, where n is the number of an unused trunk group. For the compliance test, trunk group number 1 was chosen. On Page 1, set the fields to the following values: Set the Group Type field to sip. Choose a descriptive Group Name. Specify an available trunk access code (TAC) that is consistent with the existing dial plan. Set the Service Type field to tie. Specify the signaling group associated with this trunk group in the Signaling Group field as previously specified in Step 5. Specify the Number of Members supported by this SIP trunk group. As mentioned earlier, each SIP call between two SIP destinations (whether internal or external) requires two SIP trunks for the duration of the call. Thus, a call between two SIP extensions, e.g., two telephones behind the AudioCodes MP- 124, will use two SIP trunks. A call between a SIP extension and the PSTN will only use one SIP trunk. The default values may be retained for the other fields. add trunk-group 1 Page 1 of 21 TRUNK GROUP Group Number: 1 Group Type: sip CDR Reports: y Group Name: siproute COR: 0 TN: 1 TAC: 701 Direction: two-way Outgoing Display? n Dial Access? n Night Service: Queue Length: 0 Service Type: tie Auth Code? n Signaling Group: 1 Number of Members: 100 7.

Configure a route pattern that is routing to its outbound SIP proxy server (Avaya SES server). This will be assigned on the locations screen. Refer to Step 9. The example below shows the route pattern used in the reference test configuration. The Pattern Name can be any descriptive name. The Grp No. is set to the trunk- group number for the trunk to be used. The FRL field defines the facility restriction level for this route pattern. The value of 0 is the least restrictive. Default values for all other fields can be used. change route-pattern 1 Page 1 of 3 Pattern Number: 1 Pattern Name: siproute SCCAN? n Secure SIP? n Grp FRL NPA Pfx Hop Toll No. Inserted DCS/ IXC No Mrk Lmt List Del Digits QSIG Dgts Intw 1: 1 0 n user 2: n user 3: n user 4: n user 5: n user 6: n user 9. Use the change locations command to assign the route pattern to the location. This screen allows for each location to point to the route pattern that is routing to its outbound SIP proxy server. This correlation is required by features and services such as Transfer and URI Dialing. Only one location created by default, known as Main, exists for the service provider data center and the customer sites. Enter the route pattern number from the previous step in the Proxy Sel.

Configure SIP Stations The analog endpoints (e.g. analog telephones, fax machines and modems) behind the AudioCodes MP-124 are considered SIP stations from the point of view of Avaya Communication Manager. This section describes the steps for configuring SIP stations. Support for SIP stations that use SIP trunks allows any fully compliant SIP telephone to interoperate with Avaya telephones. This means that any SIP telephone can: • Dial and be dialed as an extension in the enterprise dial plan. • Put calls on hold and participate in transfers and conference calls. SIP stations that are administered as Outboard Proxy SIP stations, also known as off-PBX station (OPS) stations, support most Extended Access Features, such as call park, call pick-up, and priority calls. To activate these features, either dial Feature Access Codes or dial special extensions, that is, Feature Name Extensions. For more details, see Avaya Extension to Cellular User’s Guide, Issue 6, DocID 210-100-700, and the Avaya Extension to Cellular and OPS Installation and Administration Guide, Issue 8, DocID 210-100-500. The configuration for Feature Access Codes and Feature Name Extensions is not in the scope of this document. These steps were performed using the SAT at the service provider data center in the configuration shown in Figure 1 to add the OPS stations.

  22. 22. BS; Reviewed: SPOC 9/20/2006 Solution & Interoperability Test Lab Application Notes ©2006 Avaya Inc. All rights reserved. 22 of 44 AudioCodes-SIP.doc Step Description 7. Inbound SIP calls arriving at Avaya SES are routed to the appropriate Avaya Communication Manager for termination services. This routing is specified in a Media Server Address Map configured on Avaya SES. This routing compares the Uniform Resource Identifier (URI) of an incoming INVITE message to the pattern configured in the Media Server Address Map, and if there is a match, the call is routed to the designated Avaya Communication Manager. The URI usually takes the form of sip:user@domain, where domain can be a domain name or an IP address. Patterns must be specific enough to uniquely route incoming calls to the proper destination if there are multiple Avaya Media Servers supported by the Avaya SES server. In this test configuration, some of the incoming calls from customer sites require a Media Server Address Map entry. For example, in the test configuration, 3-digit numbers beginning with digit 8 were configured as the Avaya Communication Manager Feature Access Codes. From customer sites, the user portion of the SIP URI will contain the Feature Access Code. An example of a SIP URI in an INVITE message received from a customer site would be: sip: 841@192.168.10.50. In this example, the user portion is the Feature Access Code (FAC) 841. Thus, the media server address map strategy was to define pattern matches for 8xx in the URI, where x is any digit between 0 and 9, and have Avaya SES forward the messages that match to the appropriate media server. To configure a Media Server Address Map: Expand the Media Servers option in the left pane of the administration web interface and select List. This will display the List Media Servers page. Click on the Map link associated with the appropriate media server to display the List Media Server Address Map page. Click on the Add Map In New Group link. The page shown below is displayed. The Host field displays the name of the media server to which this map applies. Enter a descriptive name in the Name field. Enter the regular expression to be used for the pattern matching in the Pattern field. The example below shows the pattern specification for Feature Access Codes ^sip:8[0-9]{2}. This expression will match any SIP URI that begins with the text string sip:8 followed by a 2-digit string. Based on the value of the Host field, these SIP calls will then be routed to host S8500clan.

All rights reserved. 43 of 44 AudioCodes-SIP.doc APPENDIX A: Specifying Pattern Strings in Address Maps The syntax for the pattern matching used within Avaya SES is a Linux regular expression used to match against the URI string found in the SIP INVITE message. Regular expressions are a way to describe text through pattern matching. The regular expression is a string containing a combination of normal text characters, which match themselves, and special metacharacters, which may represent items like quantity, location or types of character(s). In the pattern matching string used in Avaya SES: Normal text characters and numbers match themselves. Common metacharacters used are: o A period . matches any character once (and only once). o An asterisk * matches zero or more of the preceding characters. o Square brackets enclose a list of any character to the matched. Ranges are designated by using a hyphen. Thus, the expression [12345] or [1-5] both describe a pattern that will match any single digit between 1 and 5. o Curley brackets containing an integer ‘n’ indicate that the preceding character must be matched exactly ‘n’ time. Thus, 5{3} matches ‘555’ and [0-9]{10} indicates any 10 digit number. o The circumflex character ^ as the first character in the pattern indicates that the string must begin with the character following the circumflex. Putting these constructs together as used in this document, the pattern to match the SIP INVITE string for any valid 1+ 10 digit number in the North American dial plan would be: ^sip:1[0-9]{10} This reads as: “Strings that begin with exactly sip:1 and having any 10 digits following will match. A typical INVITE request below uses the shaded portion to illustrate the matching pattern. INVITE sip:17325551638@20.1.1.54:5060;transport=udp SIP/2.0
