Voice Quality Monitoring (VQM)

Voice quality monitoring feature allows the IP 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 IP phones support two mechanisms for
voice quality monitoring: RTCP-XR and VQ-RTCPXR.
