asterisk voip drupal

I'm engaging a client on a community network, and I've garnered some interest in a VoIP piece, namely, the ability for instant communication regarding meeting schedules. The part of my proposal that caught their attention was:

As far as I can tell, our site www.forestlake.ca is currently the only working example of asterisk drupal integration. I would love to be disabused of this notion, so if there are other working sites out there, please let us know.

At any rate you can read about the "Forest Lake Telephone Company" at this posting on drupal .org: http://drupal.org/node/59187 or you can just register and try it out on the forest lake site. Go to : http://forestlake.ca/forestlake/?q=node/466 for instructions on trying it out.

The good news in all this is that I have an asterisk server all ready and working with Drupal. If you want to install and test the asterisk integration module developed by Malthus, you can do so by downloading and installing the asterisk module (http://drupal.org/project/asterisk) on your site. (Important, as far as I know, the asterisk integration module only works so far on 4.6. I do not know what plans Malthus might have to upgrade).
