VOIP Dispatch
VOIP Dispatch

The latest Communications Truck is equipped with Voice Over IP radio dispatch capabillity. The system uses Telex C-Soft Console Software to control a cabinet of 10 Motorola radios via Telex IP-223 interface boxes. The Analog transmit and receive audio signals to/from the radios are digitized and supplied to network by the IP-223. The software is Windows based but is running on Apple Mac Mini computers, selected for its ruggedness, reliability, quietness, low heat generation and small footprint. Windows is loaded onto the Mac computers to run the Telex software. There are two VOIP dispatch stations, each equipped with touch-screens, headsets and foot pedal PTT switches.

The radio stack accessable by the VOIP dispatch software consists of the following:

Two Motorola XTL-5000 trunking radios in the 800mhz band which are programmed to communicate with adjacent agencies including City of Roseville, City of Folsom, City and County of Sacramento, California State Parks and California Department of Transportation (Cal Trans).
