Call Statistics Fields
Table 41: Call Statistics Fields
DescriptionField
Type of voice stream received (RTP streaming audio): G.729, G.722/iLBC,
G.711 u-law, G.711 A-law, or Lin16k.
Rcvr Codec
Type of voice stream transmitted (RTP streaming audio): G.729,
G.722/iLBC, G.711 u-law, G.711 A-law, or Lin16k.
Sender Codec
Size of voice packets, in milliseconds, in the receiving voice stream (RTP
streaming audio).
Rcvr Size
Size of voice packets, in milliseconds, in the transmitting voice stream.Sender Size
Number of RTP voice packets received since voice stream was opened.
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.
Note
Rcvr Packets
Number of RTP voice packets transmitted since voice stream was opened.
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.
Note
Sender Packets
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).
Avg Jitter (value1/value2)
Maximum jitter observed since the receiving voice stream was opened.Max Jitter
Number of RTP packets in the receiving voice stream that have been
discarded (bad packets, too late, and so on).
The phone discards payload type 19 comfort noise packets that
are generated by Cisco Gateways, which increment this counter.
Note
Rcvr Discarded
Missing RTP packets (lost in transit).Rcvr Lost Packets
