AT&T IP Flexible Reach Service Nortel BCM50 Release 3.0 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. VoIP trunks use line numbers 001 to 012.
AT&T IP Flexible Reach Service Nortel BCM50 Release 3.0 SIP Configuration Guide Figure 4: 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 BCM50. This can be done by going to Administration Æ General Æ Service Manager, and restarting the “feps” service.
AT&T IP Flexible Reach Service Nortel BCM50 Release 3.0 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.

AT&T IP Flexible Reach Service Nortel BCM50 Release 3.0 SIP Configuration Guide 5 Troubleshooting This section provides some tips about troubleshooting problems 5.1 System Monitoring with BCM Monitor A valuable application for performance monitoring is the BCM Monitor. It allows the BCM administrator to see the current status of various parts of the BCM system.
AT&T IP Flexible Reach Service Nortel BCM50 Release 3.0 SIP Configuration Guide The BCM Monitor application can be downloaded to an administrator’s PC from the BCM and pointed at a specific BCM’s IP address for monitoring. Multiple instances of the BCM Monitor application can be used on a single PC to monitor several remote BCM systems at the same time. Backward version compatibility is supported. All of the registered IP devices can be viewed with the BCM Monitor.
AT&T IP Flexible Reach Service Nortel BCM50 Release 3.0 SIP Configuration Guide Figure 25: RTP Session Information The BCM Monitor can be used to monitor incoming and outgoing trunks to determine if trunks are being busy or if they are idle. The example below depicts utilized lines used by local and remote telephone/DN numbers. Figure 26: Line Monitor Information The BCM Monitor can also be used to monitor all types of system usages.

The entire log files required to diagnose a problem is consolidated into a single file.
AT&T IP Flexible Reach Service Nortel BCM50 Release 3.0 SIP Configuration Guide 6 APPENDIX A: Configuring Destination Code with Wildcard In an inbound call scenario, the leading digit sent to the BCM50 may be the same as the digit used in the destination code. Without configuring for a wildcard; the BCM50 will interpret the call as a tandem call, and will fail to terminate the call on the BCM50. To remedy this, it is recommended to configure destination code with wildcard.
