Description
Number of RTP voice packets that were transmitted since voice stream
opened.
This number is not necessarily identical to the number of RTP voice
Note
packets that were transmitted since the call began because the call
might have been placed on hold.
Estimated average RTP packet jitter (dynamic delay that a packet encounters
when going through the network), in milliseconds, that was observed since
the receiving voice stream opened.
Maximum jitter, in milliseconds, that was observed since the receiving voice
stream opened.
Number of RTP packets in the receiving voice stream that were discarded
(bad packets, too late, and so on).
Note The phone discards payload type 19 comfort noise packets that Cisco
Gateways generate, because they increment this counter.
Missing RTP packets (lost in transit).
Total number of concealment frames divided by total number of speech
frames that were received from start of the voice stream.
Ratio of concealment frames to speech frames in preceding 3-second interval
of active speech. If using voice activity detection (VAD), a longer interval
might be required to accumulate 3 seconds of active speech.
Highest interval concealment ratio from 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 5 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.
