rtp-rtcp > base-udp-
port
[BaseUDPport]
used for RTP, RTCP (RTP port + 1) and T.38 (RTP port + 2). For
more information on configuring the UDP port range, see
Configuring RTP Base UDP Port on page 183.
The range of possible UDP ports is 6,000 to 65,535. The default
base UDP port is 6000.
Note: For the parameter to take effect, a device reset is required.
rtcp-act-mode
[RTCPActivationMode]
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 the Gateway application.
No-Op Packets Parameters
no-operation-enable
[NoOpEnable]
Enables the transmission of RTP or T.38 No-Op packets.

[0] = Disable (default)

[1] = Enable
This mechanism ensures that the NAT binding remains open
during RTP or T.38 silence periods.
[NoOpInterval] 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.
no-operation-interval
[RTPNoOpPayloadType]
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.
RTP Control Protocol Extended Reports (RTCP XR) Parameters
For more information on RTCP XR, see Configuring RTCP XR on page 881.
Enable RTCP XR
configure voip > media rtp-rtcp
> voice-quality-monitoring-
enable
[VQMonEnable]
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.
Minimum Gap Size
[VQMonGMin]
Defines the voice quality monitoring - minimum gap size (number
of frames).
The default is 16.
