|
| |
Rcvr Lost Packets | Total number of RTP data packets that have been lost since starting receiving | |
|
| data on this connection. Defined as the number of expected packets less the |
|
| number of packets actually received, where the number of received packets |
|
| includes any that are late or duplicate. The value displays as 0 if the |
|
| connection was set to |
|
|
|
Avg Jitter |
| Estimate of mean deviation of the RTP data packet |
|
| measured in milliseconds. The value displays as 0 if the connection was set to |
|
| |
|
|
|
Rcvr Codec |
| Type of audio encoding used for the received stream. |
|
| |
Rcvr Reports Sent1 | Number of times the RTCP Receiver Reports have been sent. | |
Rcvr Report Time | Internal time stamp indicating when a RTCP Receiver Report was sent. | |
Sent1 |
|
|
Rcvr Packets |
| Total number of RTP data packets received by the phone since starting |
|
| receiving data on this connection. Includes packets received from different |
|
| sources if this is a multicast call. The value displays as 0 if the connection was |
|
| set to |
|
|
|
Rcvr Octets |
| Total number of payload octets received in RTP data packets by the device |
|
| since starting reception on the connection. Includes packets received from |
|
| different sources if this is a multicast call. The value displays as 0 if the |
|
| connection was set to |
|
|
|
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 |
|
| |
|
| “Monitoring the Voice Quality of Calls” section on page |
|
| 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. |
