Call Park not working 8851 phone mgcp gateway.

[Stewart Thomas]

Just changed out some SCCP phones for newer SIP 8851. Everything works, but have crazy issue with call park. Call park works fine IP phone to IP phone. When a call comes in the MCGP gateway via PRI. I Park the incoming call no issue. Retrieve the parked call no issue. I can do this twice. On the third time I park the call the call gets disconnect. This is only happening on Sip phones not SCCP phones at this Particular MGCP gateway.

Seems like it is time to pull the logs of CUCM and see what message is being sent with the disconnect and see if any know bugs exist.

Well I pulled debug isdnq931 off of gateway.  Seems as if the telco is disconnecting call. Just don't see how this could be a telco issue. I've seen stranger things though.

The provider is responding to the NOTIFY Message. Can we have complete isdn q931, What happens when you hold 1st and 2nd time?

*** Please rate helpful post; if applicable
