I just wanted to mention because of the topic of this question: Using VOIP with Perl will be one of the two presentations given at the next Los Angeles Perl Mongers meeting. The presentation is entitled, "Mike Frager: VOIP with perl and asterisk/freepbx". Anyone in the LA area interested follow the link for specifics.

To everyone else (not in LA): Find the Perl Mongers group nearest you!

I realize this presentation will probably be too late and/or too far away for the person who asked this question. So if Mike makes the slides available online I'll (with his permission) follow up to this post with a link to them. At least then it will only be too late (no longer too far), and hopefully a future reader may benefit.
