What IP address do you normally build the SIP trunks to on a CUCM?

Hi All

When building SIP trunks from my CUCM, we only have phones registered to 2 subscribers and not our pub.

I see when calls are made across the trunk they come from the subscriber IP, never the publisher IP.

What do you normally do here? is this normal behaviour? do we need to add the pub IP and 2 subs in from the remote end?

Cheers

Any node in the cluster that has the Call Manager service enabled should be defined as a IP on the SIP trunk on the remote end. Further more recommendations would be to enable Run on all nodes on the SIP trunk to get an optimal traffic path.
