
[4] = The device allocates ports in "jumps" of 4 ports.

[5] = (Default) The device allocates ports in "jumps" of 5
ports.

[10] = The device allocates ports in "jumps" of 10 ports.
Note:

A device reset is required for the parameter to take effect.

For more information on configuring the UDP port range, see
Configuring RTP Base UDP Port on page 195.
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.
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.
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 OVOC (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
OVOC (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).
