SQmediator Symphony is a suite of performance management applications for Voice over IP and IP video conferencing. SQmediator is a sophisticated multi-user management system that supports both passive QoE monitoring and active testing, and provides per-location or per-customer dashboards. SQmediator is the first performance management application to support the new RFC 6035 collector function that allows IP phones and gateways to report end-to-end QoE through SIP. SQmediator can control DVQattest active test agents and APP-DVQ-5/10/50/100/200 active test appliances, initiating on-demand or scheduled tests and collecting and displaying test results. Test agents can be associated with customers, locations, network entities or equipment, allowing test results to be correlated and displayed on the SQmediator dashboard. SQmediator supports active tests for VoIP, videoconferencing, Web, email, DNS, DHCP and IP transport. SQmediator can generate both SNMP and e-mail alert notifications to notify network personnel of problem conditions. Email alert preferences can be configured by severity and on a per-user basis.
