Description
Number of milliseconds for delay in the RTP-to-RTP
interface round trip.
Number of packets lost.
The fraction of RTP data packets from the source lost
since the beginning of reception. Defined in
RFC-3611—RTP Control Protocol Extended Reports
(RTCP XR).
The fraction of RTP data packets from the source lost
since the beginning of reception. Defined in
RFC-3611—RTP Control Protocol Extended Reports
(RTCP XR).
The fraction of RTP data packets from the source that
have been discarded since the beginning of reception,
due to late or early arrival, under-run or overflow at
the receiving jitter buffer. Defined in
RFC-3611—RTP Control Protocol Extended Reports
(RTCP XR).
The mean duration, expressed in milliseconds, of the
burst periods that have occurred since the beginning
of reception. Defined in RFC-3611—RTP Control
Protocol Extended Reports (RTCP XR).
The mean duration, expressed in milliseconds, of the
gap periods that have occurred since the beginning of
reception. Defined in RFC-3611—RTP Control
Protocol Extended Reports (RTCP XR).
Voice quality metric that describes the segment of the
call that is carried over this RTP session. Defined in
RFC-3611—RTP Control Protocol Extended Reports
(RTCP XR).
The estimated mean opinion score for listening quality
(MOS-LQ) is a voice quality metric on a scale from
1 to 5, in which 5 represents excellent and 1 represents
unacceptable. Defined in RFC-3611—RTP Control
Protocol Extended Reports (RTCP XR).
The estimated mean opinion score for conversational
quality (MOS-CQ) is defined as including the effects
of delay and other effects that affect conversational
quality. Defined in RFC-3611—RTP Control Protocol
Extended Reports (RTCP XR).
