Enabling Vad; Configuring Options Related To Dial Plan - HP FlexNetwork MSR Series Configuration Manual

Enabling VAD

The voice activity detection (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%.
To enable VAD:
Step
1. Enter system view.
2. Enter voice view.
3. Enter voice dial program
view.
4. Create a POTS voice entity
and enter POTS voice entity
view.
5. Enable VAD.
