Voice over Internet Protocol Bridging

Public safety agencies are investing millions in devices that allow agencies to patch non-interoperable LMR systems together. Many of these bridging systems use VoIP technology. While IP itself is a formal standard that allows for interoperability, the VoIP technology built on top of that standard is often proprietary and prevents interoperability.

The PSCR program is leading a coalition of public safety officials and bridging systems vendors to ensure that disparate LMR systems can interoperate using today’s VoIP technologies. This coalition has developed a BSI implementation profile, which is the minimum set of standards, parameters, and values required to achieve interoperable implementations.
