RxType |
| Type of voice stream received (RTP streaming audio): G.729, |
|
| G.722/iLBC, G.711 |
|
|
|
TxType |
| Type of voice stream transmitted (RTP streaming audio): G.729, |
|
| G.722/iLBC, G.711 |
|
|
|
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 may not be identical to the number of RTP |
|
| voice packets transmitted since the call began because the |
|
| call might have been placed on hold. |
|
| |
Avg Jitter (value1/value2) | Estimated average RTP packet jitter (dynamic delay that a packet | |
|
| encounters when going through the network). |
|
| • Value1 is the average jitter in milliseconds (ms). |
|
| • Value2 is the current audio frame buffer depth in m). |
|
|
|
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 discards payload type 19 comfort noise packets |
|
| that are generated by Cisco Gateways, which increment this |
|
| counter. |
|
| |
Rcvr Lost Packets | Missing RTP packets (lost in transit). | |
