Introduction This document describes the quick start configuration of Nortel Secure Router 2330/4134 (Release 10.2) as survivable branch SIP-PSTN gateway for Nortel Communication Server 1000 (Release 6.0). For more information and detailed configuration guides on SR 2330, SR 4134 and CS 1000 go to the Nortel website: www.nortel.
SR 2330/4134 interoperability with CS 1000 SR 2330/4134, CS 1000 components The following diagram shows the main components of Secure Router 2330/4134 Communication Server 1000. and SR has two modules SIP Gateway (SIP GW) and SIP Survivability Module (SSM) that together interworks with CS 1000 to provide SIP survivable gateway functionality at the branch. SSM is a software-only subsystem on the Secure Router through which SIP calls are routed to the CS 1000.
For detailed information on CS 1000 components and operation please refer to Communication Server 1000 Release 6.0 user guides. SSM Operation The SSM operates in two modes - Normal (Connected) and Survivable (Isolated). In normal mode, the SSM functions as an outbound proxy and proxies all SIP messages initiated from the SIP phones (UA) and the SIP GW to the SLG located in the head office. SSM acts as a B2BUA i.e. changes the Contact Header of SIP endpoint requests.
ensure that incoming calls are routed through the SSM. The same call flow holds good for the call originated by the SIP endpoint connected to CS 1000. When the call arrives at SSM, it will look for a mapped contact in its registration “cache” and routes the call to the UA. If SSM does not find the mapped contact then it forwards the call to the configured default gateway. The following diagram shows the call flow between two SIP endpoints in branch in Normal (Connected) mode.
SSM will receive the incoming calls from SPS that are destined for PSTN. For such calls SSM will not be able to find a mapped contact in its registration cache and hence routes the call to configured default gateway which is SIP GW. The following diagram shows the call flow between a branch PSTN interface/device and branch SIP endpoint.
The following diagram shows the call flow between branch PSTN interfaces/devices.
CS 1000 Configuration This section describes the configuration steps needed on CS 1000 components like SLG, SSG and SPS for SR 2330/4134 based branch solution. There is no SR 2330/4134 specific configuration required on CS 1000. Please refer to CS 1000 user guides for the detailed configuration steps. The following diagram complete with IP addresses will be used as reference for the configuration chapters.

SSG Configuration Please refer to CS 1000 document for detailed information on SSG configuration. SIPL needs a SSG server to route an external call to NRS (Network Routing Service). SIPGW and H323GW endpoints will be configured in SSG to register on specific NRS server.

NRS/SPS Configuration Please refer to CS 1000 NN43001-130 Network Routing Service Fundamentals document for detailed information on NRS/SPS configuration. The Network Routing Service (NRS) provides routing services to both SIP and H.323-compliant devices. The NRS allows customers to manage a single network dialing plan for SIP, H.323, and mixed SIP/H.323 networks. Therefore SIPGw and H323Gw endpoints of SSG and Secure Router endpoint have to register on NRS server.

8) SR 2330/4134 endpoint registration status Figure NRS 7 – SR 2330/4134 endpoint registration status SIP Clients Configuration Configure the branch SIP endpoints to use SSM bind IP address as the Outbound Proxy ie.100.20.42.80:5060. Please ensure that the SIP username and domain need to match the CS 1000 SIP Line settings. username@domain represents a globally unique identifier for a SIP user. CS 1000 Patches Below patches are needed for version CS: 600R LB: 6.00.18 LA: 6.00.
SR 2330/4134 Configuration This section describes the configuration steps needed for SR 2330/4134 for CS 1000 branch solution. The following diagram complete with IP addresses will be used as reference for this chapter. For configuration details on SSM, please refer to Secure Router Release 10.2 guide NN47263-510 Configuration — SIP Survivability. For configuration details on SIP Gateway (SIP GW) please refer to Secure Router Release 10.2 guide NN47263-508 Configuration — SIP Media Gateway. Steps 1.
2. Configure a default route to the branch router: ip route 0.0.0.0/0 100.20.42.65 3. Configure the SIP Media Gateway to listen on port 5070: voice service voip sip bind all ipv4:100.20.42.80:5070 exit sip exit voip 4. To configure the SIP Survivability Module, bind the IP interface for SIP traffic using default port 5060: voice service voip ssm bind ip ipv4:100.20.42.80 5. Enable SSM: enable 6. Configure dialpan.
cac max-calls ethernet0/1 256 10. Configure the CAC exclusion pool that identifies the IP address range of the SIP endpoints that use SSM: exclude-pool 100.20.47.0 255.255.255.0 exit cac 11. Point the SSM to the SIP Media Gateway IP interface as the default gateway (specifying the non-default port), Port should be same as configured for gateway’s listening port in step 3.: default-gateway ipv4:100.20.42.80:5070 transport udp exit ssm exit voip 12.
no shutdown exit voice-port voice-port 2/2 signal loop-start station number 74002 no shutdown exit voice-port 18. Configure PRI interface bundle. (example to configure PRI E1 bundle on port 3/1 with switch-type as qsig) interface bundle E1PSTN link pri_e1 3/1 voice isdn switch-type primary-qsig activate exit isdn exit bundle 19. Optional translation profile configuration. a. Configure translation profile for PSTN to SPS calls. (Example to translate 335.. number to 5.. numbers.
20. Configure Dial peer for FXS phones: dial-peer voice pots 1 destination-pattern 74001 port 2/1 forward-digits all no shutdown exit pots dial-peer voice pots 2 destination-pattern 74002 port 2/2 forward-digits all no shutdown exit pots 21. Configure Dial peer for PRI interface and (optionally) apply translation profile. (Following dial peer is for calls coming from SPS with a number starting with 53 to be translated to a number starting with 3353 before sending on PRI.
