Astograph is a simple python tool to represent visually your Asterisk dialplan
It uses GraphViz to draw the links between included contexts
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)
Here is another example, written in the Digium Advanced Training Class:
