Item Description
Route Selection
Priority
Set the priority of the call route. The smaller the value, the higher the priority.
VAD
The VAD discriminates between silence and speech on a voice connection according
to their energies. VAD reduces the bandwidth requirements of a voice connection by
not generating traffic during periods of silence in an active voice connection. Speech
signals are generated and transmitted only when an active voice segment is detected.
Researches show that VAD can save the transmission bandwidth by 50%.
• Enable.
• Disable.
By default, VAD is disabled.
