RTCP Summary Reports
The IP phones include the capability of enabling/disabling the generation of
RTCP summary reports using the SIP vq-rtcpxr event package. These RTCP
summary reports include voice quality statistics according to
draft-ietf-sipping-rtcp-summary-05 specifications including packet loss, jitter, and
delay statistics, as well as call quality scores. When this feature is enabled, an
RTCP summary report is sent at the end of each call via a PUBLISH message to
the configuration server.
In addition to enabling/disabling the generation of these reports, you must specify
the hostname and port of the entity, known as the collector, receiving the reports.
Similar to the other IP Phone SIP account parameters, the RTCP summary report
parameters can be set on a global or a per-line basis using the configuration files
only.
The RTCP summary report parameters are:
•
sip rtcp summary reports
•
sip LineN rtcp summary reports
•
sip rtcp summary report collector
•
sip LineN rtcp summary report collector
•
sip rtcp summary report collector port
•
sip LineN rtcp summary report collector port
Limitations
The following is a limitation when enabling RTCP summary reports on the phone:

extended reports.
