• The RTCP XR DLRR report block can be sent in response to a Receiver Reference Time block so that a receiver which is not sending media can calculate its round trip time. in context
• The RTCP XR VoIP Metrics block reports end system delay separately from network round trip delay, in milliseconds. in context
• The RTCP XR VoIP Metrics block reports the current nominal jitter buffer delay and the current maximum jitter buffer delay, both in milliseconds. in context
• The RTCP XR VoIP Metrics report block carries a round trip delay field: the most recently calculated round trip time between RTP interfaces, in milliseconds. in context
• Halving an RTCP round-trip figure gives only the network part of one-way delay and assumes a symmetric path; mouth-to-ear delay also includes end-system delay such as codec and jitter buffer, so it will be higher than RTT/2. inferred in context
