I thought the Cisco UCM zone had to be a client, not a server.

Yup, Expressway Control is definitely the traversal server in the DMZ.

Wait, can you really NAT both Expressway-E interfaces? Sounds off.

Totally agree, the Unified Communications zone is key for MRA.

The Expressway-E must be in a DMZ, that's a must!

Okay, I think I've got this. Based on the information provided, the incorrect server URL seems like the most likely cause of the problem.
