Would need detailed CCM Traces to determine the exact cause, but you may be hitting CSCsh40465, which is fixed in 5.1(3).

And by detailed CCM traces I mean - detailed CCM traces of a phone registering on the CCM side, and a call out the SIP Trunk.

Hello, I am facing the same issue with Nortel interop:

Nortel CS1000M --> (IP) Cisco VG --> Call Manager 6

Calls got established but DTMF not transmitted. Do I need to upgrade the VG to CUBE IOS?

Any other options available to solve the interop issue?

Appreciate your feedback.

Thanks,

Wil
