I have configured CME 4.1 to act as SIP Proxy Server,Configured it corectly so X-Lite SIP Softphone can register with it. Inside LAN network X-Lite to X-Lite calls function without the problem, but:
I connect through VPN to my LAN and register X-Lite with CME (extenssion 66) without any problem.
The other person also connects to our LAN through and registers his X-Lite with CME (extenssion 55).I would like them to talk to each other.
The problem is following. When any of us try to call eachother, the X-Lite Rings, and when a call is answered it immediatly drops with error "Internal Server Error". This is SIP 500 message.
Does anybody has a clue why is this happening and how it can be solved.
