Porblem with E1 controlled by MGCP

Unanswered Question
Oct 12th, 2009


I have a problem with an E1 access controlled by mgcp, some calls are connected and others no, and the cause is : Cause i = 0x87A2 - No circuit/channel available.

I have a full E1 access with 30 channels, i have this problem for incomming and outgoing calls.

Thanks to help

Any pattern?

New install?

what CUCM and IOS version?

Every time it fails same destination?

Which codec in use?

Whats the call flow?

Check fi you get any DSP error

I would collect:

debug voice ccapi ino

debug mgcp packet

debug isdn q931

CUCM SDI/SDL detailed traces
