Call Statistics Items

Item

Description

Rcvr Codec

Type of voice stream received (RTP streaming audio from codec): G.729,

G.728/iLBC, G.711 u-law, G.711 A-law, or Lin16k.

Sender Codec

Type of voice stream transmitted (RTP streaming audio from codec):

G.729, G.728/iLBC, G.711 u-law, G.711 A-law, or Lin16k.

Rcvr Size

Size of voice packets, in milliseconds, in the receiving voice stream (RTP

streaming audio).

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 9-16

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.
