About this task
Avaya Aura® MS uses the QualityRating to indicate audio quality for a session.
The QualityRating (range 0-100) is updated periodically for each active session. The rating is based on the negotiated codec in use and factors in the quality of the packet stream as it is transported over the network. Each codec has an individual maximum quality value. Wideband codecs have a higher maximum QualityRating value than narrowband codecs.
See Quality of Service (QOS) Troubleshooting for further information on sources of QOS issues.
