CME T1 CAS caller id

Answered Question
Mar 30th, 2009

We have recently installed a CME system running IOS 12.4.22.T1. CME version is 7.0. We have a T1 CAS using all 24 channels. Is there a way to get caller id to display on inbound calls?

I have this problem too.

T1 CAS doesn't support caller-id. Some providers will offer it as a supplementary service via DTMF in the *ANI*CLID format, but this isn't supported on the ISR routers.

You can get caller ID via CAS FGD ports. I would ask your provider if this is an option.

We are using a VWIC2-1MFT-T1/E1 card so you're config might vary slightly if you are using something else.

I omitted the unimportant stuff. Here is the part that matters. You'll want to talk to the provider to see what kind of signaling they will be using on the T1 CAS. In this case they were using wink start.

card type t1 0 1

controller T1 0/1/0
