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 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.
Avg Jitter
(value1/value2)
Estimated average RTP packet jitter (dynamic delay
that a packet encounters when going through the
network).
• Value 1 is the average jitter in milliseconds (ms).
• Value 2 is the current audio frame buffer depth
in millisecond (ms).
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 will discard payload type 19
comfort noise packets that are generated by
Cisco Gateways, which will increment this
counter.
Rcvr Lost Packets Missing RTP packets (lost in transit).
