MGCP PRI Outbound Busy

I did a firmware upgrade which went without issue. However, after it was done, the facility stated that they were not able to make outbound calls, inbound worked fine.

I did a no mgcp, and that resolved the issue. My question is: Should I treat this as coincidence or could it have to do with the firmware upgrade having an adverse affect on the callmanager?

The upgrade consisted of 141 phones.

Re: MGCP PRI Outbound Busy

i don't believe the issue was due to the firmware since they run over a whole different protocol, phones SCCP, GW MGCP.

What was the status of the GW under CUCM? registered, unregistered, unknown?

Did you gather a debug isdn q931 to look at the reason code for the disconnect?
