13 PBX Extension Transceiver Controller Telephone Connection screen PBX Extension > Transceiver Controller Telephone Connection ■■PTT Control Setting The VOX (voice operated transmission) function automatically switches the connected transceiver to transmit, when the RoIP gateway receives an audio signal through the network. 1 2 3 4 1 Attack Time 2 Release Time 3 Voice Delay 4 VOX Threshold Enter the TX delay time. (Default: 50) •• Range: 5 ~ 500 (milliseconds) in 5 millisecond steps After the continuous signal for the set period of time is received from a SIP phone, the transceiver controller starts to transmit. Select the RX delay time. (Default: 500) •• Range: 5 ~ 2000 (milliseconds) in 5 millisecond steps This is the delay time for the VOX to turn OFF, after no audio signal is received through the network. Set the audio signal buffer time to prevent intermittent audio.  (Default: 200) •• Range: 0 ~ 1500 (milliseconds) in 5 millisecond steps The voice delay is the amount of time the RoIP gateway stores the transmitted audio to prevent missing the first part of the speech. Set the voice threshold level.  (Default: 40) •• Range: 0 ~ 100 (%) The VOX function automatically switches between receive and transmit according to this threshold level. The lower values make the VOX function more sensitive to the voice input. 13-56
