One of the systems I manage is an 875 Extension Cisco Unified Call Manager(UCM). At the moment the system uses SCAN trunks for long distance calling. These SCAN Trunks are provided by the state of Washington and interconnect via a four port FXO card. Callers use a PIN to make long distance calls. This is some seriously old school technology and as such has sound quality to match.

Sometime early in 2006 I started building systems with AA@H. About the only inexpensive way to learn Asterisk was in the forums and blogs. It was in the Nervittles blog of Ward Mundy that I won entrance to the first Fonality trixbox® Open Communications Certification (FtOCC, pronounced “F-talk”) workshop, held in LA - March 2007.
