If you are unable to make or receive calls though your Asterisk is registered, you'll need to execute commands in your Asterisk console to diagnose the issue.
To do so, please use the following two commands:
- sip set debug
- core set verbose 10
If you are still working with the Asterisk version 1.2, please use the following two commands instead:
- sip debug
- set verbose 10
Once you've entered the above commands, please make a test call. The log messages now appearing on the console should assist you in diagnosing the problem.
