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.

RTCP-XR
The RTCP-XR mechanism, compliant with RFC 3611-RTP Control Extended Reports (RTCP XR), provides the metrics con-
tained in RTCP-XR packets for monitoring the quality of calls. These metrics include network packet loss, delay metrics,
analog metrics and voice quality metrics.

RTCP-XR Configuration
RTCP-XR Configuration
The following table lists the parameters you can use to configure the RTCP-XR.
Parameter
voice.rtcp_xr.enable
[1]
<y0000000000xx>.cfg
Description It enables or disables the IP phone to send RTCP-XR packets.
Permitted Values
0-Disabled
1-Enabled
Default 0
Web UI Settings->Voice Monitoring->Voice RTCP-XR Report
Parameter
voice.rtcp.enable
[1]
<y0000000000xx>.cfg
Description It enables or disables the IP phone to send RTCP packets.
Permitted Values
0-Disabled
1-Enabled
Default 1
Parameter
voice.rtcp_cname
[1]
<y0000000000xx>.cfg
Description It configures the cname of the RTCP packets.
Permitted Values String
Default Blank
[1]
If you change this parameter, the IP phone will reboot to make the change take effect.
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.
