Configuring RTCP XR

RTP Control Protocol Extended Reports (RTCP XR) is a VoIP management control that
defines a set of metrics containing information for assessing VoIP call quality and for
diagnosing problems. RTCP XR (RFC 3611) extends the RTCP reports defined in RFC
3550 by providing additional VoIP metrics (Quality of Experience). RTCP XR information
publishing is implemented in the device according to RFC 6035. This draft defines how a
SIP User Agent (UA) publishes the detailed information to a defined collector. RTCP XR
measures VoIP call quality such as packet loss, delay, signal / noise / echo levels,
estimated R-factor, and mean opinion score (MOS). RTCP XR measures these parameters
using metrics as listed in the table below.

License Key that includes this feature. For installing a Software License Key, see
''Software License Key'' on page 599.
RTCP XR messages containing key call-quality-related metrics are exchanged periodically
(user-defined) between the device and the SIP UA. This allows an analyzer to monitor
these metrics midstream, or a device to retrieve them using SNMP. The device sends
RTCP XR reports to an Event State Compositor (ESC) server, using SIP PUBLISH
messages. These reports can be sent at the end of each call and according to a user-
defined interval between consecutive reports.
