I am currently using Call Manager 3.3.3 and a H323 Voice Gateway.
"Call Forward ALL" has been set up on an extension on the Call Manager to Forward all incoming call to an international number, however most of the time it doesnt work. The error message is "Recovery on timer expiry
I have tried to increase the T301 timer on both the Call manager and Voice gateway to 60000ms, however it still doesnt work. I have tried to increase it to a higher value but the result is the same.
The only location that its working is to CAll Forward all to Bangkok international number From Hong Kong. Other location will receive the same error " Recovery on timer expiry"
