Push to Talk over VoIP – PTToIP

Solving Push-To-Talk (PTT) Issues in VoIP Networks

REDCOM has developed a patented method of solving the problems of passing PTT signals reliably in a VoIP network

While VoIP has matured markedly to the point of widespread acceptance, it does not comprehensively address network requirements common to existing legacy networks. Despite these deficiencies, VoIP has been accepted as the de-facto standard for modern voice networks.

Traditional networks support PTT for radio keying by passing the signal in synchronization with voice communications, thus keying the radio at the appropriate time. If so equipped, network equipment designed for radio support uses industry-standard interfaces. VoIP, however, has no such support for passing PTT. Furthermore, VoIP networks have no assurance that a PTT-type control signal will reach the distant radio in order to key it at the appropriate time. This might result in the PTT signal to key a radio transmitter arriving some time after the voice packet reception has commenced.
