Voice over IP has been around for several years but has only recently reached a level suitable to replace traditional analogue phone systems. Several standards have been produced for delivering VoIP. The current standard for most VoIP systems is SIP. Like most other technologies on the internet, Linux has its fair share of quality systems that provide services for VoIP. Most notable of these is the Asterisk Software PABX.

This presentation will demonstrate the configuring of Asterisk and the basic workings of SIP.

Adrian is a Network Engineer for Speek IP Phones, a VoIP Carrier.
