Call State |
Status of the call. |
Duration |
Duration of the call. |
Remote Address |
Address of the remote device. |
Local Address |
Address of the local device. |
Start Time |
Starting time of the call |
Type |
Direction of the call. |
Peer Name |
Name of the internal phone. |
Peer Phone |
Phone number of the internal phone. |
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. |
Sender Octets |
Total number of octets sent by the phone. |
Sender Codec |
Type of voice stream transmitted (RTP streaming audio from codec): G.729, iLBC, G.711 u-law, or G.711 A-law. |
Rcvr Lost Packets |
Missing RTP packets (lost in transit.) |
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. |
Rcvr Codec |
Type of voice stream received (RTP streaming audio from codec): G.729, iLBC, G.711 u-law, or G.711 A-law. |
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 |
Rcvr Octets |
Total number of octets received by the phone. |
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. Note The MOS LQK score can vary based on the type of codec that the Cisco Unified IP Conference Phone 8831 for Third-Party Call Control 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 stream. 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.729 A /AB gives 3.7
- iLBC gives 3.9
|
MOS LQK Version |
Version of the Cisco proprietary algorithm used to calculate MOS LQK scores |
Cumulative Conceal Ratio |
Total number of concealment frames divided by total number of speech frames received from start of the voice stream. |
Interval 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. |
Max Conceal Ratio |
Highest interval concealment ratio from start of the voice stream. |
Conceal Secs: |
Number of seconds that have concealment events (lost frames) from the start of the voice stream (includes severely concealed seconds). |
Severely Conceal Secs |
Number of seconds that have more than 5 percent concealment events (lost frames) from the start of the voice stream. |
Latency |
Number of milliseconds for latency. |
Max Jitter |
Number of milliseconds for receiver jitter. |
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. |
