Yes absolutely you can use MGCP with T1 CAS. In the CallManager select CAS as the protocol.

How would it backhaul q931 messages, there are no q931 messages on a T1-CAS.

q931 does not apply to CAS

But here is a doc with example config

You are correct.

T1CAS uses other signalling we actually support E&M wink start and dealy dial.

Note that when using 6608 Blade with T1 CAS configured the signalling will be as follows:

PSTN --> T1 CAS -- 6608 --- ISDN Q931 BH Messages to CCM.

The blade will convert ISDN Q931 BH messages from|to CCM into CAS messages.
