Unable to register Cisco 7965/7942 with CME 9.1 -HELP

Below are the configuration details and debug output from the CME router. Please help me resolve this issue.... (i have changed the IP addresses/DID for security reasons)

hello,

hello,

If phones register fine locally, then it's a network/ connectivity issue where I recommend you to dig further.

Thank you,

Shadi
