Description
Number of times the RTCP Receiver Reports have
been sent.
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.
