Hi,
I've a CUCM 5.1 with an MGCP GW. This GW makes a QSIG connection on a PABX. In very specific situation, I can see that my GW does not reply to a CONNECT isdn message and does not send a CONNECT_ACK.
Is there a command to force this on the Cisco GW?
Thanks

An ISDN Q931 connect should always be replied to with a connect ack. What is the 'very specific situation' you refer to that causes this problem ? Do you have a debug isdn q931 log that shows the messages - if so, please paste here.

Thabks for the answer.
The very sporadic situation is a call to an analog bipper system connected on an analog trunk on the PBX.
It appeared that the problem was a misocnfiguration on the PBX, but of course, as it's not my PBX, I can't have the real cause of the problem.
Anyway, I still don't understand why my GW didn't reply with CONNECT_ACK.
