RoIP - Radio over IP
Our RoIP software provides clear, private, and secure radio communications using VoIP protocols.

Radio over IP (RoIP) transmits radio communications over IP networks to extend the range and interoperability of radio systems.

Our RoIP design solutions provide developers a variety of platforms while our comprehensive RoIP software provides a robust and highly configurable library including a Network Stack and SIP Stack with jitter control, as well as a wide range of voice compression, echo cancellation and noise reduction algorithms. Together with secure protocols SRTPSDESIPsec, and our encryption libraries, VOCAL’s RoIP software solution can ensure clear, private, and secure radio communications.

Radio over IP Communications

Radio Over IP uses VoIP protocols to transmit radio signals over an IP network such as the public Internet. In its simplest form, radio over IP converts a RF signal to digital data suitable for transport over an IP network. An IP radio network consists of some number of radios, which may include a combination of handheld, mobile, and fixed two-way radios, along with a RoIP gateway that provides the interface to an IP network.

Radio Over IP offers numerous advantages to both existing radio networks as well as new communications systems under development.
