# How do I enable debugging in Asterisk for error evaluation?

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 or two. The log messages for these calls now appearing on the console should be able to assist you in diagnosing the problem.
