I've been using the Axon PBX for development purposes for more than a year, and up until now I've had no problems whatsoever. But recently I'm getting these messages shortly after a call is ended:
"Destination of message from user XXXX cannot be determined"
Also - and this is a bigger issue - my application no longer receives DTMF signals from the PBX. Everything else seems to be working; I can register, receive a call, it starts normally etc. My first reaction was that maybe the problem is related to the message above, but I'm not sure about that. Also, I've turned off firewalls on all the machines involved (caller, callee, server running Axon).
