incoming caller id on T-1 CAS

Unanswered Question
Jan 13th, 2008

I have a callmgr 5.1 with Unity 5.0. Incoming service is via a T-1 CAS, e&m-wink start ckt.

Incoming call hits unity auto attendant and transfers to user. IP phone rings an ddisplay shows "unknown number".

Should display show caller id assuming carrier is sending it? If so, is there any config needed to enable it? How can I verify carrier is sending it?

gateway is mgcp-2821.



I have this problem too.

usually T1 CAS in itself doesn't support caller-id, and then MGCP again doen't as well.

As you telco for PRI on the circuit, reconfigure router and CCM, and you will have caller-id.

Hope this helps, please rate post if it does!
