Voice Quality Monitoring (VQM)
Voice quality monitoring feature allows the phones to generate various quality metrics for listening quality and con-
versational quality. These metrics can be sent between the phones in RTCP-XR packets. These metrics can also be
sent in SIP PUBLISH messages to a central voice quality report collector. Yealink phones support two mechanisms
for voice quality monitoring: RTCP-XR and VQ-RTCPXR.
Topics
RTCP-XR
VQ-RTCPXR
RTCP-XR
The RTCP-XR mechanism, compliant with RFC 3611-RTP Control Extended Reports (RTCP XR), provides the met-
rics contained in RTCP-XR packets for monitoring the quality of calls. These metrics include network packet loss,
delay metrics, analog metrics, and voice quality metrics.
