Branch Gateway supports the RTP-MIB feature for debugging QoS-related problems across the VoIP network without any specific hardware. In each RTP stream, counters representing various QoS metrics increase when the configured metrics thresholds are exceeded. Branch Gateway stores a limited history of the QoS metric statistics for active and terminated RTP streams. You can use the Branch Gateway CLI to view the statistics.

You can also configure Branch Gateway to send SNMP traps to the SNMP trap manager on an Avaya server at the session termination of each RTP stream that has QoS problems. The Communication Manager SNMP trap manager converts traps to syslog messages and stores them on the Avaya server hard disk.
