Re: Dropped calls MGCP Temporary Failure

I have the same issue, but it happens to all my handsets if the is silence on the line. Can anyone point me in the right direction to fix this issue?

Re: Dropped calls MGCP Temporary Failure

To Clarify, My issue is when you call a specific DID from outside, CM sends a disconnect message back and drops the call. Internally the extensions works fine and calls can be made outside from this extension.
