Status Menu

Sender Size Size of voice packets, in milliseconds, in the transmitting voice

stream.

Rcvr Packets Number of RTP voice packets received since voice stream was

opened.

Note This number is not necessarily identical to the number of

RTP voice packets received since the call began because the

call might have been placed on hold.

Sender Packets Number of RTP voice packets transmitted since voice stream was

opened.

Note This number is not necessarily identical to the number of

RTP voice packets transmitted since the call began because

the call might have been placed on hold.

Avg Jitter Estimated average RTP packet jitter (dynamic delay that a packet

encounters when going through the network) observed since the

receiving voice stream was opened.

Max Jitter Maximum jitter observed since the receiving voice stream was

opened.

Rcvr Discarded Number of RTP packets in the receiving voice stream that have been

discarded (bad packets, too late, and so on).

Note The phone will discard payload type 19 comfort noise

packets that are generated by Cisco Gateways, which will

increment this counter.

Rcvr Lost Packets Missing RTP packets (lost in transit).

Voice Quality Metrics

MOS LQK Score that is an objective estimate of the mean opinion score (MOS)

for listening quality (LQK) that rates from 5 (excellent) to 1 (bad).

This score is based on audible concealment events due to frame loss

in the preceding 8-second interval of the voice stream. For more

information, see the “Monitoring the Voice Quality of Calls” section

on page 9-15.

Note The MOS LQK score can vary based on the type of codec

that the Cisco Unified IP Phone uses.

Avg MOS LQK Average MOS LQK score observed for the entire voice stream.

Min MOS LQK Lowest MOS LQK score observed from start of the voice stream.

Max MOS LQK Baseline or highest MOS LQK score observed from start of the

voice strea m.

These codecs provide the following maximum MOS LQK score

under normal conditions with no frame loss:

• G.711 gives 4.5

• G.722 gives 4.5

• G.728/iLBC gives 3.9

• G.729 A/AB gives 3.8
