Description
Item
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.
Avg jitter
Maximum jitter, in milliseconds, that was observed since the receiving voice
stream opened.
Max jitter
Number of RTP packets in the receiving voice stream that were discarded
(bad packets, too late, and so on).
The phone discards payload type 19 comfort noise packets that Cisco
Gateways generate, because they increment this counter.
Note
Receiver discarded
Missing RTP packets (lost in transit).
Receiver lost packets
Voice-Quality Metrics
Total number of concealment frames divided by total number of speech
frames that were received from start of the voice stream.
Cumulative conceal ratio
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.
Interval conceal ratio
Highest interval concealment ratio from start of the voice stream.
Max conceal ratio
Number of seconds that have concealment events (lost frames) from the start
of the voice stream (includes severely concealed seconds).
Conceal seconds
Number of seconds that have more than 5 percent concealment events (lost
frames) from the start of the voice stream.
Severely conceal seconds
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.
Latency
Display Current Access Point Window
The Current Access Point screen displays statistics about the access point that the Cisco IP Phone 8861 uses
for wireless communications.
describes the information that appears in this screen.
