Description
Internal time-stamp indication as to when a RTCP Receiver Report was sent.
Total number of RTP data packets that the phone has received since data
reception started on this connection. Includes packets that were received from
different sources if this call is a multicast call. The value displays as 0 if the
connection was set to send-only mode.
Total number of payload octets that the device received in RTP data packets
since reception started on the connection. Includes packets that were received
from different sources if this call is a multicast call. The value displays as 0 if
the connection was set to send-only mode.
Total number of concealment frames divided by total number of speech frames
that were received from the start of the voice stream.
Ratio of concealment frames to speech frames in the preceding 3-second interval
of active speech. If voice activity detection (VAD) is in use, a longer interval
might be required to accumulate three seconds of active speech.
Highest interval concealment ratio from the start of the voice stream.
Number of seconds that have concealment events (lost frames) from the start
of the voice stream (includes severely concealed seconds).
Number of seconds that have more than five percent concealment events (lost
frames) from the start of the voice stream.
Estimate of the network latency, expressed in milliseconds. Represents a running
average of the round-trip delay, measured when RTCP receiver report blocks
are received.
Maximum value of instantaneous jitter, in milliseconds.
RTP packet size, in milliseconds, for the transmitted stream.
Number of times RTCP Sender Reports have been received.
Most recent time when an RTCP Sender Report was received.
RTP packet size, in milliseconds, for the received stream.
RTP packets that were received from the network but were discarded from the
jitter buffers.
