I have recently upgraded our CUCM cluster to v9.1 and would like to integrate fully with our VCS (control and expressway) for SIP URI calls.
I have followed Cisco documentation and configured the following
- SIP trunk from the CUCM to VCSC
- Neighbour zone on the VCSC pointing at the CUCM Pub & Sub
- Route pattern on CUCM for ‘*’ pointing to the VCS SIP trunk
- Search rule on VCSC matching addresses assigned to CUCM users and pointing to the CUCM zone
The following calls work with no issues.
CUCM Registered Endpoint -> VCS Registered Endpoint
VCS Registered Endpoint -> CUCM Registered Endpoint
VCS Registered Endpoint -> External Endpoint
External Endpoint -> VCS Registered Endpoint
External Endpoint -> CUCM Registered Endpoint
However calls from CUCM registered devices to external destinations fail
CUCM Registered Endpoint -> External Endpoint
I can see logs on both the VCSC and VCSE which are as follows.

Does this mean that the DNS lookup has not worked correctly? The same addresses are reachable from VCSC registered endpoints.
Does the VCSE treat calls originating from CUCM differently?
If anyone can point me in the right direction then I would be grateful.
Many Thanks
