Panoramisk is a library based on python's AsyncIO to play with Asterisk's manager.
It uses the TCP manager server to listen to events and send actions.
For basic usage, you have some examples in examples/ folder.
A webapp for administering Asterisk from a web browser. Written in PHP. Worked on recently. Asterisk's API doesn't change very much so there probably doesn't need to be. Backed by MySQL. No obvious documentation so it'll need to be messed with to get installed.
