This might be the wrong email list for this kind of question. The MGCP list at the

Softswitch Consortium (www.softswitch.org) or at pulver.com would be more appropriate.

The answer is -- wrong idea. MGCP is a device control protocol, not a signalling protocol.

You wouldn't try to map Q.931 to MGCP except some simplistic notions of connections.

This would be local to a particular softswitch implementation, and thus not standardized.

You can ask how the Q.931 gets from the gateway to the softswitch. It isn't over MGCP!

Generally, the accepted notion is that the MG terminates Q.921, and uses SCTP and IUA

to transport Q.931 to the Call Agent, which terminates the Q.931 messages, creating the

appropriate MGCP commands to make the right connections. The Call Agent might have

to map Q.931 to whatever protocol it uses to connect to another Call Agent. That might be

ISUP (Q.BICC to be exact), H.323, or SIP.

Subject: Q.931 package for MGCP?

Anyone aware of a Q.931 package for MGCP? I am interested in mapping Q.931 to MGCP.
