Voice quality monitoring feature allows the IP phones to generate various quality

metrics for listening quality and conversational 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. Two mechanisms for voice quality

monitoring are supported by Yealink IP phones:

 RTCP-XR

 VQ-RTCPXR

The RTCP-XR mechanism, complaint with RFC 3611-RTP Control Extended Reports

(RTCP-XR), provides the metrics 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.
