VOIP Communication

Replace your radio chatter with clear, direct communication.

Enhanced communication and connectivity

Voice Over Internet Protocol (VOIP) is an emerging technology that has recently begun to see applications within the transit industry over recent years. VOIP replaces the standard radio communications with press-to-talk (PTT) capabilities that provide clearer, more direct channels to speak with dispatch without a message share across multiple vehicles. The technology leverages the cellular service used by the installed ITS to manage connections with the home base.

SPOT’s VOIP solution represents a clear advantage to transit agencies who seek to improve connectivity and situational awareness between vehicle and dispatch, enhance the clarity and quality of communications, and deliver faster, more precise responses to field-generated concerns.
