If you encounter telephony issues with your Asterisk, 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.
