VQ-RTCPXR
The VQ-RTCPXR mechanism, compliant with RFC 6035, sends the service quality metric reports contained in SIP
PUBLISH messages to the central report collector.
A wide range of performance metrics are generated in the following three ways:
l Based on current values, such as jitter, jitter buffer max and round trip delay.
l Covers the time period from the beginning of the call until the report is sent, such as network packet loss.
l Computed using other metrics as input, such as listening Mean Opinion Score (MOS-LQ) and conversational Mean
Opinion Score (MOS-CQ).
