G.722/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 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).
