ISDN Overlap MGCP

Can someone tell me what I need to configure on an mgcp gateway to enable ISDN Overlapping?

Re: ISDN Overlap MGCP

Under the serial interface, put in:

isdn overlap-receiving

Re: ISDN Overlap MGCP

This isn't quite right because a large portion of the serial interface configurations do not apply for MGCP since CUCM does all of the Q.931 signaling.

This is controlled via a service parameter on CUCM:

Overlap Receiving Flag for PRI. It's TRUE by default. There's another one for H323 if you're interested.
