VoIP and SIP Radio Solutions

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 decentralized radio infrastructure that is flexible, provides a lower cost of ownership and facilitates improved interoperability.
