cdspVadAdaptive

Module: CISCO-DSP-MGMT-MIB

OID (symbolic): CISCO-DSP-MGMT-MIB::cdspVadAdaptive

OID (numeric): 1.3.6.1.4.1.9.9.86.1.4.1.1.5

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: This attribute is used to enable or disable the Adaptive VAD knob of the VAD algorithm. Adaptive VAD works in conjunction with VAD Threshold (cvifcfgMusicOnHoldThreshold from CISCO-VOICE-IF-MIB). When this object set to 'true', VAD Threshold is ignored and the DSP adjusts the threshold automatically according to the background noise level. When the adaptive VAD configuration is 'false', VAD threshold is used directly. The VAD configuration is ignored for all CODECs that contain their own VAD (G.729AB, G.723.1A and GSM-EFR). Likewise, when a channel is configured in ClearChannel mode (Clear Channel is Non-Compression CODEC channel), VAD will automatically be disabled irrespective of the configuration.

What is cdspVadAdaptive?

A read-write toggle that enables or disables Adaptive Voice Activity Detection (VAD); when enabled it overrides the fixed VAD threshold setting and dynamically adjusts silence detection.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.86.1.4.1.1.5
snmpwalk -v2c -c public <target> CISCO-DSP-MGMT-MIB::cdspVadAdaptive

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.86.1.4.1.1.5.1
snmpget -v2c -c public <target> CISCO-DSP-MGMT-MIB::cdspVadAdaptive.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.86.1.4.1.1.5.1 s <value>
