I am setting up a SIP to PRI on a 924e. I need to be able to accept calls from any one of 5 IP addresses and place outbound calls to a single IP with a secondary/failover. Can someone assist me with this? I am able to do the SIP to PRI to a single IP just not sure how to accept from many and send to one.
Create five voice trunks, one for each IP. Set up registration and authentication as needed. On the one that is the primary outbound path, create a voice grouped-trunk with the appropriate outbound dial patterns and a cost of 0. On the secondary one do the same with a cost greater than 0.
