The Power of VoIP and SIP Technologies

Voice over IP (VoIP) technology is expanding the capabilities of two-way radio communication services through Local Area Networks (LAN) and Wide Area Networks (WAN). VoIP has enabled the implementation of a decentralised radio infrastructure that is flexible, provides a lower cost of ownership and facilitates improved interoperability.

The benefits of using VoIP for radio communications have been greatly enhanced through the introduction of the Session Initiation Protocol (SIP). The adaptation of SIP into the world of land mobile radio has opened the door for new and innovative interfacing, dispatch and interoperability solutions. This powerful and widely accepted protocol is the preferred method of designing and operating modern radio communications networks.

SIP is commonly used in the VoIP telephone world for creating, modifying, and terminating sessions with one or more users. SIP can be used to create two-party, multi party or multicast sessions and is based on an RFC standard from the Internet Engineering Taskforce. It is now considered the number one protocol due to its simplicity, flexibility and ease of use, and is fast becoming the common language in the convergence of voice and data applications.

Providers of Radio Over IP technology are standardising on SIP because it enables the real time confi guration of audio connections between VoIP gateway products, including consoles. In effect this creates distributed audio bridges and dispatch systems that can be controlled from remote locations in real time.

Omnitronics has carefully combined SIP with other technologies that have been specifi cally tailored for Land Mobile Radio. This includes RTP/RTCP and our proprietary digital audio conferencing technology. Together, these enable VoIP connections to remote radios to be established and managed.
