tag=1c1690611502;from-tag=1c2032864069To configure RTCP XR:
1. Open the RTP/RTCP Settings page (Configuration tab > VoIP menu > Media >
RTP/RTCP Settings). The RTCP XR parameters are listed under the RTCP XR
Settings group:
Figure 52-1: RTCP XR Parameters in RTP/RTCP Settings Page
2. Under the RTCP XR Settings group, configure the following:
• 'Enable RTCP XR' (VQMonEnable) - enables voice quality monitoring and RTCP
XR.
• 'Burst Threshold' (VQMonBurstHR) - defines the voice quality monitoring
excessive burst alert threshold.
• 'Delay Threshold' (VQMonDelayTHR) - defines the voice quality monitoring
excessive delay alert threshold.
• 'R-Value Delay Threshold' (VQMonEOCRValTHR) - defines the voice quality
monitoring end of call low quality alert threshold.
• 'Minimum Gap Size' (VQMonGMin) - defines the voice quality monitoring
minimum gap size (number of frames).
• 'RTCP XR Packet Interval' (RTCPInterval) - defines the time interval between
adjacent RTCP reports.
• 'Disable RTCP XR Interval Randomization' (DisableRTCPRandomize) -
determines whether RTCP report intervals are randomized or whether each
report interval accords exactly to the parameter RTCPInterval.
3. Under the RTCP XR Setting - SIP Collection group, configure the following:
• (Gateway Application Only) 'Gateway RTCP XR Report Mode'
(RTCPXRReportMode) - determines whether RTCP XR reports are sent to the
ESC server and defines the interval at which they are sent.
