Radio over IP (RoIP) and connecting push to talk radios to SIP
Vocality's latest film shows BASICS Radio Relay connecting different radio networks, as well as connecting into a media server or switch for cross connecting into different IP voice platforms. This is the essential RoIP gateway platform for emergency services, defence and field deployed services.

Beyond Line-of-Sight (LOS)
Devices such as BASICS Radio Relay or BASICS Hybrid allow the direct connectivity of several handsets into the unit, and the push to talk radio conversation and associated signalling is converted into IP.
Unlike a straightforward gateway application, the BASICS units have a special functionality that cannot be found in other gateways. Vocality's PACE functionality allows the radio calls to be extended over IP with the maximum reliability, but the minimum of bandwidth overhead.
A combination of silence suppression, packet aggregation, de-jittering and efficient but clear voice compression bring significant bandwidth savings to the network operator, and importantly, the calls are clearer and more reliable to the user. In this way, users can extend a PTT radio network over -
Mobile satellite terminals (Thuraya+, Inmarsat BGAN)
Field deployed tactical IP (via line of site connectivity, satcom or fiber)
Terrestrial IP (extend radio networks for ambulance, taxi or emergency comms)
Communications Gateway
Vocality supports Radio Over IP (RoIP) allowing a number of push to talk radio handsets to be connected locally into an existing SIP based voice switching network, such as...
CISCO Call Manager or Juniper VoIP
Asterisk PBX
WAVE 5000 from Motorola (formerly WAVE from Twisted Pair)
Commercial SIP based VoIP PBXs
In this way, a push to talk network can interface with existing VoIP handsets, can connect calls onward to phones or mobile phones on the PSTN, to smartphones and to specialist PTT Android or iOS applications.

Cross-banding Interoperability
By connecting multiple radios on different bands into a Vocality solution, different radio networks can be cross-connected.
By using this solution, different agencies or blue light services can have an easy and effective way to interconnect their service, removing the possibility that their services cannot work together in the case of an event.
Remote Control
By using either in-band E&M signalling, or by using a data circuit (sync or async) carried alongside the radio extension or gateway, remote radio networks can be controlled from a central location.
