I stumbled upon Asterisk a month or so for OSX, and immediately built it on my laptop to make calls between multiple Cisco SIP phones, and I couldn't believe how fantastic it was. With a tool like this, it makes managing and owning an OSX PBX a great reality, and not only am I planning on implementing Asterisk in my new home, but I'm building a system based on OSX for my office of 30 employees.

Keep up the good work
