ccasIfExtVoiceCfgVadTimer
Module: CISCO-CAS-IF-EXT-MIB
OID (symbolic): CISCO-CAS-IF-EXT-MIB::ccasIfExtVoiceCfgVadTimer
OID (numeric): 1.3.6.1.4.1.9.9.314.1.1.1.1.14
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object specifies the hangover time for VAD.
Once the voice inactivity is detected, gateway will wait for this duration before activating silence suppression.
What is ccasIfExtVoiceCfgVadTimer?
This sets the VAD hangover time in milliseconds, how long the gateway waits after detecting silence before it actually activates silence suppression on this voice interface. A hangover time that is too short can clip the trailing syllables of speech as silence suppression kicks in prematurely, while one that is too long delays the bandwidth savings VAD is meant to provide, so this is tuned specifically against perceived call-quality complaints. An admin might raise this from a 250 ms minimum to 500 ms after users report choppy-sounding call endings, giving VAD more margin before muting the channel.
