We recently upgraded our phone system to CCUM 7.0
Our Main site is connected via SIP trunk to Verizon.
We have remote branches configured via MGCP across MPLS to the Main Site CUCM.
Each branch has a PRI for all inbound calls (outside company site to site) and local outbound calls.
Each branch is using the Main Site SIP trunk for Long Distance, across the MPLS.
All other branches seem to be working ok.
One branch several times has lost the ability to make any outbound call, local or Long Distance.
Inbound calls are working ok, site to site calls are working ok.
The Gateway shows up as "Status:Ready" in CUCM.
On the Gateway it shows MGCP as registered, nothing in the log
Since I am new to voice, anyone want to share a troubleshooting check list I could go through?
It seems to be something within CUCM, since both local and LD are affected (two seperate paths) and inbound calls are working.
