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.
Solved! Go to Solution.
yes, I have configured it with the command
voice class codec 1
codec preference 1 g711alaw
codec preference 2 g711ulaw
and then under voice poolvalso
voice-class codec 1
I have also to mention following.
When I connect from one location using VPN and registering to CME with IP Communicator and from other Location using VPN and registering X-Lite, calls can be placed between IP Communicator and X-Lite.
The only issue is X-Lite to X-Lite (SIP to SIP) calls
In X-Lite I have set only G711a and G711u codecs, but it was not working.
When I set only G711u codec it worked.
Thanx very much
I will grade it with 5 ;-)
