Astograph

Astograph is a simple python tool to represent visually your Asterisk dialplan

It uses GraphViz to draw the links between included contexts

Example

Considering this extensions.conf file:

and the following command:

cat extensions.conf | ./astograph.py | dot -Tpng:cairo > graph.png

Make sure you have GraphViz installed for dot, and you should get this:

Dotted lines mean Possible Gotos and solid lines mean Context inclusions.

You can pipe a bunch of extensions.conf files (if you've splitted them with #includes)
