If someone wants to give this a try, the wrapper to run asterisk
(and other graphic apps) within firefox is available at


In order to run asterisk in a window:
- build asterisk with console_video support.
  You need to have installed the following packages:
	libsdl1.2-dev, libsdl-image1.2-dev
	libavcodec-dev, libswcale-dev
  then apply this patch to channels/Makefile

- install asterisk, and copy images/kpad2.gif and images/font.png
  to /tmp

- modify oss.conf adding the following at the end:
	    keypad = /tmp/kpad2.jpg
	    keypad_font = /tmp/font.png

- test asterisk running from the command line 'asterisk -vdc'
  you should see the gui coming up.

- install app-wrapper.so into ~/.mozilla/plugins
- write a file ~/.mozilla/plugins/app-wrapper.conf with this content
	application/x-asterisk:ast:embedded asterisk: /path/to/asterisk -vd

- create a local file /tmp/a.ast - it can be empty
- start firefox and point it to file:///tmp/a.ast
