I've used 3cx before and got some problems with it, so i've found the problems, reinstalled 3cx with the latest version and now i want to use it "live". But i'm running against a problem. Incoming calls works 100% fine, but when i try an outgoing call, nothing happens. No tone, nothing. When i look into the log it says the following: 10:20:24.001 Call::Terminate [CM503008]: Call(10): Call is terminated 10:20:10.079 CallLeg:nFailure [CM503003]: Call(10): Call to sip:firstname.lastname@example.org:5060 has failed; Cause: 408 Request Timeout; internal 10:19:37.455 CallCtrl:nSelectRouteReq [CM503004]: Call(10): Calling: VoIPline:10000@[Dev:sip:email@example.com:5060, Dev:sip:firstname.lastname@example.org:5060, Dev:sip:email@example.com:5060] What could this be? (i've tried removing and reinstalling 3cx, but that not works) The firewall test says: Passed.
