I was successfully configured outbound call with the same goautodial machine for testing but suddenly it is showing the carrier UNREACHABLE. After searching on internet I got this command to enable debug ‘sip set debug’

The Result in Asterisk CLI is given as follows:

Please help me to solve this.


Could you provide a complete capture of your SIP traffic? I.e. start listening on your network interface with ngrep or whatever, place call, stop capture. Post that.

Unreachable results when OPTIONS requests produce no response. Even a rejection is a response. The qualify option enables this behaviour.
