Asterisk CLI Commands

At work we setup Asterisk PBX phone systems along with our own Perl scripts for various purposes. Asterisk is an open source PBX phone system that works with Soft Phones and Hard Phones. I installed and setup Asterisk on my work laptop with a software VoixPhone (SIP/IAX).

The one thing with Asterisk is that each update introduces a few changes, mainly the choice of CLI commands to debug or find certain information.

This post is basically a quick reference to the current Asterisk CLI commands. If you are interested in taking a look at Asterisk (it’s in the Debian repos) and/or the VoixPhone software SIP/IAX phone, see these links:
