cvVoIPCallHistoryChannels
Module: CISCO-VOICE-DIAL-CONTROL-MIB
OID (symbolic): CISCO-VOICE-DIAL-CONTROL-MIB::cvVoIPCallHistoryChannels
OID (numeric): 1.3.6.1.4.1.9.9.63.1.4.2.1.44
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The object indicates the number of audio channels. Supported value is 1. This object is not instantiated when the object cvVoIPCallHistoryCoderTypeRate is not equal to gsmAmrNb enum.
What is cvVoIPCallHistoryChannels?
This Integer32 (1-6 channels) indicates the number of audio channels used for an AMR-NB call, with 1 being the only supported value, and it is only instantiated for the gsmAmrNb coder. Administrators use it mainly as a sanity check that AMR-NB calls are being handled as mono audio as expected, since multi-channel audio isn't actually supported. For example, this object consistently reading 1 across all AMR-NB call records confirms the gateway isn't attempting unsupported multi-channel encoding.
