The RTCP XR packets are compliant with RFC 3611 - RTP Control Extended
Reports (RTCP XR). The packets are sent to a report collector as specified in
draft RFC draft-ietf_sipping_rtcp-summary-02.
Three types of quality reports can be enabled:
• Alert—Generated when the call quality degrades below a configurable
threshold.
• Periodic—Generated during a call at a configurable period.
• Session—Generated at the end of a call.
A wide range of performance metrics are generated. Some are based on
current values, such as jitter buffer nominal delay and round trip delay, while
others cover the time period from the beginning of the call until the report is
sent, such as network packet loss. Some metrics are computed using other
metrics as input, such as listening Mean Opinion Score (MOS), conversational
MOS, listening R-factor, and conversational R-factor.
Configuration changes can be performed centrally at the provisioning server:
Specify the location of the central report collector, how often the
reports are generated, and the warning and critical threshold values
that will cause generation of alert reports.

Dynamic noise reduction (DNR) provides maximum microphone sensitivity,
while automatically reducing background noise— from fans, projectors,
heating and air conditioning—for clearer sound and more efficient
conferencing.
There are no related configuration changes.
The treble and bass controls equalize the tone of the high and low frequency
sound from the speakers.
The SoundStation IP 7000 phone's treble and bass controls can be modified by
the user (through Menu > Settings > Basic > Audio > Treble EQ or Bass EQ).
Configuration changes can be performed centrally at the provisioning server:
Specify the user's preferences for treble and bass.
