VComp Trace Options

Last Updated : Nov 19, 2019 |

This tab provides trace options for monitoring the system's voice compression channels. Note that these options produce a large amount of trace records and so should be used with caution.

These options are only available when the Development Tracing option is selected in the Filters > Trace Options > System menu, see System Trace Options. They are not covered by this document as they are used by Avaya for product trials and are subject to frequent changes.

These options should only be used under the guidance of an authorized Avaya development engineer.

General VCM Trace Options


Option	Description
Command Send	Log details of commands transmitted to the voice compressor chip.
Command Receive	Log details of commands received from the voice compressor chip.
Data Send	Log details of data transmitted to the voice compressor chip (additional detail from the Command Send option).
Data Receive	Log details of data received from the voice compressor chip (additional detail from the Command Receive option).
Print on Stuck	Log a summary trace if the system detects a severe problem.
Summary Trace	Log the commands to and from all the voice compressor chips (multiple occurrences are counted to reduce output) and the output is controlled so as not to swamp the system. Care should be exercised when selecting this option - especially if multiple VoIP calls are in progress.
