Mozilla's open source phone system
What does Mozilla - arguably the most popular open source project in the world - use for its telephony solution?
It shouldn't surprise you that they use a solution built in open source should it?
When I was at Mozilla's Toronto office - I made sure to check out all the 'flashing lights' and being an admitted geek I like to see what kind of phone systems people use (no I know nothing about phone phreaking....).
Mozilla developer Mike Beltzner answered my questions (or tried too..thnx Mike!) about Mozilla's use of Asterisk...check out the little vid below of the exchange.
