RTP and RTCP statistics 63
When a file reaches the 16 K limit, it is closed and the next file is opened.
When EM retrieves the log file, a function on the card concatenates the
four files in file date order and the resulting file is sent. EM retrieves and
displays each file separately.

RTP and RTCP statistics
Three CLI commands, RTPStatShow, RTPTraceShow and
RTPTraceStop, relate to real-time RTCP statistics. Upon issuing the
CLI command RTPStatShow or RTPTraceShow to an IP Phone, the
RTCP statistics report appears on the Signaling Server TTY port or Telnet
session. RTPStatShow requests a snapshot of RTCP statistics versus
RTPTraceShow requests RTCP statistics for a certain number of polling
periods or until the end of the call. RTPTraceStop stops RTPTraceShow.
Both RTPStatShow and RTPTraceShow request an active IP Phone for
RTCP statistics information. The only difference is that RTPStatShow
requests a snapshot of RTCP statistics information but, RTPTraceShow
periodically requests refreshed RTCP statistics information for a certain
amount of time.
