ViaTalk PBX is an VoIP/web application that powers support calls for ViaTalk, HostRocket, and DotBlock. The application handles routing incoming calls to support queues, call detail record logging, and displaying an overview of past and current calls. I was responsible for the entire application including server setup and maintenance. The backend VoIP application was designed using Asterisk and MySQL. The web application was designed using PHP, CodeIgniter, and MySQL. ViaTalk PBX served 500-1000 of daily support calls and had nearly perfect uptime under my care.
