Module: ZhoneAAL2-MIB

OID (symbolic): ZhoneAAL2-MIB::aal2VclAudioService

Description: The service provided is the transfer of audio signals (voice, voiceband data, and facsimile).

The data unit traversing the SAP (SSCS SDU) contains either a voice encoding or a silence encoding. Silences are conveyed across the SAP either explicitly by a Silence Insertion Descriptor (SID) data unit, or implicitly by a Null data unit.

Valid values are: - enabled. - disabled. - enabledEchoCancelOff: audio service enabled with echo cancellation and silence supression off. - enabledDynamic: audio service enabled with ability to dynamically disable silence supression, silence detection, echo cancellation and compression algorithms on a per-call basis.

What is aal2VclAudioService?

Sets the default audio (voice/voiceband-data/fax) service mode for channels on this VCL: enabled for normal operation, disabled to turn audio off, enabledEchoCancelOff to disable echo cancellation and silence suppression, or enabledDynamic to allow those features to be toggled per call.
