Description
Size of voice packets, in milliseconds, in the
transmitting voice stream.
Number of RTP voice packets that were received since
voice stream opened.
This number is not necessarily identical to
Note
the number of RTP voice packets that were
received since the call began because the
call might have been placed on hold.
Number of RTP voice packets that were transmitted
since voice stream opened.
Note This number is not necessarily identical to
the number of RTP voice 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.
