AT&T IP Flexible Reach Nortel BCM450 Release 1.0 SIP Configuration Guide 4.2 IP Trunks Voice over IP (VoIP) trunks, are signaling channels that simulate how CO lines work. However, VoIP trunks transmit data to the IP network over a LAN or IP network rather than over physical lines. Once the VoIP trunks are set up, you can assign them to line pools, and program their behavior in the same way you would PRI lines.
AT&T IP Flexible Reach Nortel BCM450 Release 1.0 SIP Configuration Guide Figure 3: Available VoIP Trunks Note: If no active VoIP lines are present, check to see if either SIP or IP Trunks licenses are installed. If so, try restarting the “feps” service on the BCM450. This can be done by going to Administration Æ General Æ Service Manager, and restarting the “feps” service.
AT&T IP Flexible Reach Nortel BCM450 Release 1.0 SIP Configuration Guide Under Configuration Æ Telephony Æ Dialing Plan; select “Line Pools” In this case we selected “BlocA” under the “Pool” tab. We will use this line pool to access the VoIP trunks. Additionally, all DN numbers that need to access the VoIP trunks must be added to this pool. In other words, ensure that the DN numbers have the same line pool assigned as the VoIP trunks (in Figure 4).
AT&T IP Flexible Reach Nortel BCM450 Release 1.0 SIP Configuration Guide Under Configuration Æ Telephony Æ Dialing Plan Æ Public Network, we define the Public Received number length to “4” digits and Public network dialing plan to “National.” This tells the BCM450 to look at the last four digits of a public received number, and alert the assigned DN of an incoming call.
AT&T IP Flexible Reach Nortel BCM450 Release 1.0 SIP Configuration Guide Under Configuration Æ Telephony Æ Dialing Plan Æ Routing: Select the “Routes” tab and ensure there is an entry for “BlocA” with DN Type “National.” In this case “001” is the route number and the DN Type is specified as “National.” See figure below.

AT&T IP Flexible Reach Nortel BCM450 Release 1.0 SIP Configuration Guide 6 APPENDIX A: Configuring Destination Code with Wildcard In an inbound call scenario, the leading digit sent to the BCM450 may be the same as the digit used in the destination code. Without configuring for a wildcard; the BCM450 will interpret the call as a tandem call, and will fail to terminate the call on the BCM450. To remedy this, it is recommended to configure destination code with wildcard.
