Version 7.2 1105 Mediant 1000B Gateway & E-SBC
User's Manual 65. Configuration Parameters Reference
Parameter Description
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 911.

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.
Burst Threshold
[VQMonBurstHR]
Defines the voice quality monitoring - excessive burst alert
threshold.
The default is -1 (i.e., no alerts are issued).
