Remote Source Address Mask Filtering
The Remote Source Address Mask Filtering feature is described in the “Remote Source Address Mask Filtering” section on page
RTP Specific Behavior Support
This feature adds support for the
Terminations representing gates for RTP traffic typically require two streams per media (one for RTP packets, one for RTCP packets).
Setting the property value to OFF overrides the default DBE behavior in the following ways:
•The DBE does not open the RTCP port for the given RTP flow. However, the RTCP port is not available for use by other flows.
•The DBE does not reserve additional resources (equal to 5 percent of those required for the RTP flow) for processing the RTCP stream.
DBE Restrictions
The following is a restriction of DBE support for this feature:
•Enabling or disabling this property value is only valid for RTP flows. It is ignored for other types of flows.
ServiceChange Notification for Interface Status Change
This feature enables the media gateway (MG) to generate a ServiceChange H.248 notification to the media gateway controller (MGC) containing the termination ID of the physical interface on the data border element (DBE) when the interface experiences status changes. The termination ID is a
Although notification of interface status changes can be obtained via SNMP, this feature provides a more reliable transport than SNMP and consolidates the information on the MGC for simpler management.
The MGC is also referred to as a signaling border element (SBE).
In order for the SBE to be informed about status changes on a physical interface on the DBE, you can use the sbc
