AT&T IP Flexible Reach Service

Nortel BCM50 Release 3.0 SIP Configuration Guide

Backup to a secondary AT&T IP Border Elements is supported on the BCM50 using the SIP “OPTIONS” keep-alive approach. The BCM50 will send SIP “OPTIONS” messages to the AT&T IPBEs listed in the Outbound Proxy Table and send VoIP calls based on whether or not the BCM50 receives a “200 OK” from the IPBEs and the Load-balancing Weights values set for each entry.

A Load-balancing weight of 0 means the IPBE is used as last resort. Any non- zero number value indicates the ratio of calls (the specific IPBE’s load-balancing weight to sum of all IPBE’s load-balancing weights) the BCM50 will send out to each IPBE. In this example, the BCM50 will send 1 call for every 1 call made (in essence, all calls) to the IPBE with IP address 135.25.29.135 and use 135.25.29.79 IPBE as backup.

Additionally, the AT&T IP Flexible Reach service will send incoming calls to the BCM50 from multiple IP border elements. The BCM50 will accept calls from any border element without additional configuration.
