Call Statistics Screen
The Call Statistics screen displays counters statistics and voice quality metrics in
these ways:
• During call—You can view the call information by pressing the ? button twice
rapidly.
• After the call—You can view the call information captured during the last call
by displaying the Call Statistics screen.
Note You can also remotely view the call statistics information by using a web
browser to access the Streaming Statistics web page. This web page
contains additional RTCP statistics not available on the phone. For more
information about remote monitoring, see
Chapter 8, “Monitoring the
Cisco Unified IP Phone Remotely.”
A single call can have multiple voice streams, but data is captured for only the last
voice stream. A voice stream is a packet stream between two endpoints. If one
endpoint is put on hold, the voice stream stops even though the call is still
connected. When the call resumes, a new voice packet stream begins, and the new
call data overwrites the former call data.
TX Retransmit Number of packets that have been retransmitted to
the expansion module
TX Buffer Full Number of packets discarded because the expansion
module was not able to accept new messages
