during RTP or T.38 silence periods.
Defines the time interval in which RTP or T.38 No-Op packets are
sent in the case of silence (no RTP/T.38 traffic) when No-Op
packet transmission is enabled.
The valid range is 20 to 65,000 msec. The default is 10,000.
Note: To enable No-Op packet transmission, use the NoOpEnable
parameter.
Defines the payload type of No-Op packets.
The valid range is 96 to 127 (for the range of Dynamic RTP
Payload Type for all types of non hard-coded RTP Payload types,
refer to RFC 3551). The default is 120.
Note: When defining the parameter, ensure that it doesn't cause
collision with other payload types.
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: The 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 the 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).
