CME to CME Calls Failing over GRE Tunnel

Currenlty have 2 CME systems.

System A is running IOS 15.1(3)T2

System B is running IOS 12.4(11)XJ4

System A dials a 3 digit extension and connects to system B with no issues

System B dials a 3 digit extension and cannot connect to system A

The GRE Tunnel is up and everything is pingable from either side

When system B calls a 3 digit extension on system A I see the traffic hitting system A but do not see why the call is not being connected.

CME to CME Calls Failing over GRE Tunnel

System A was recently upgraded to the 15.x IOS build

Is there something in the 15.x IOS that is retricting these calls from being connected to the IP phones?

Hi Aaron,

Thanks for the link that was the issue, I could not find it looking through the features of 15.1(3)T.
