DENVER--Radio-over-IP solutions vendor Catalyst Communications Technologies announced during APCO Version 4.42 of its software that adds capabilities designed to let users better control and manage their RoIP dispatch and interoperability systems.

The new capabilities include: the ability to link up to eight different radio systems regardless of manufacturer or frequency; the ability to transmit pre-recorded .WAV files over the air; and the ability to “cross mute” audio from a neighboring remote client, which reduces feedback into the neighboring remote client’s microphone during a transmission, the company said.

Another new application lets dispatches “tag” calls with lines of text, which is useful when trying to retrieve calls from an archive that includes thousands of calls. This feature, along with automatic time stamping of calls, provides a “simple electronic event records system,” the company said.
