The config above is not valid (registrar and proxy is not URI) but I think that's just typo since you said you can register successfully. So, registering works fine.

It's the server that fails to forward the request, so you should troubleshoot the server instead. Common reasons for this problem are unreachable Contact address registered by callee (although it doesn't seem to be the problem here since you can call it when authentication is disabled), or the INVITE packet is too big that it doesn't pass certain router. Not sure if this applies to your problem though. -benny -------------- next part -------------- An HTML attachment was scrubbed...
