Version 6.8
Disables RTCP traffic when there is no RTP traffic. This
feature is useful, for example, to stop RTCP traffic that is
typically sent when calls are put on hold (by an INVITE with
'a=inactive' in the SDP).

[0] Active Always = (Default) RTCP is active even during
inactive RTP periods, i.e., when the media is in 'recvonly' or
'inactive' mode.

[1] Inactive Only If RTP Inactive = No RTCP is sent when
RTP is inactive.
Note: This parameter is applicable only to Gateway calls (not
SBC).
Enables voice quality monitoring and RTCP XR, according to
RFC 3611.

[0] Disable (default)

[1] Enable Fully = Calculates voice quality metrics, uses
them for QoE calculations, reports them to SEM (if
configured), and sends them to remote side using RTCP
XR.

[2] Enable Calculation Only = Calculates voice quality
metrics, uses them for QoE calculations, reports them to
SEM (if configured), but does not send them to remote side
using RTCP XR.
Note: For this parameter to take effect, a device reset is
required.
Defines the voice quality monitoring - minimum gap size
(number of frames).
The default is 16.
Defines the voice quality monitoring - excessive burst alert
threshold.
The default is -1 (i.e., no alerts are issued).
Defines the voice quality monitoring - excessive delay alert
threshold.
The default is -1 (i.e., no alerts are issued).
Defines the voice quality monitoring - end of call low quality
alert threshold.
The default is -1 (i.e., no alerts are issued).
Defines the time interval (in msec) between adjacent RTCP
XR reports. This interval starts from call establishment. Thus,
the device can send RTCP XR reports during the call, in
addition to at the end of the call. If the duration of the call is
shorter than this interval, RTCP XR is sent only at the end of
the call.
The valid value range is 0 to 65,535. The default is 5,000.
Determines whether RTCP report intervals are randomized or
whether each report interval accords exactly to the parameter
RTCPInterval.
