This supplement concerns subjective quality assessment of telemeeting systems that provide audio-only or audio-visual communication for multiple parties. The term multiple parties refers to more than two meeting participants who can be located at two or more than two locations.

Evaluation of those systems can focus on audio-only, video-only or audio-visual quality aspects and non-interactive or conversational quality can be assessed.

This supplement provides example test scenarios that can be used to conduct conversation tests for multiparty audio-only telemeetings.
