DNS Radio Over IP Gateway VoIP
Quick Detail:
Brand name: DBL Type: Radio Repeater Protocol: SIP Support: Radio,VoIP, GSM, Public AnnounceDescription:
RoIP102M gateway
The fundamental of RoIP( Radio over IP) technology is to convert the audio and PTT signals in a radio terminal into IP packets and then transmit the data via the IP networks. Generally, the radio range is limited by the restricted transmitting power, antenna sensitivity and other environmental factors. RoIP technology is developed to solve those problems and insure that the audio is transmitted in real time and the PTT signals are transmitted immediately and reliably, making the long distance voice communication across multiple networks possible.
