SolarWinds VoIP & Network Quality Manager (VNQM) is a self-hosted tool for monitoring VoIP calls and WAN performance. It tracks jitter, latency, packet loss, round-trip time, and mean opinion score, with synthetic call tests and SIP trunk monitoring. Call detail and management records help locate affected calls, inspect paths, review quality metrics, and identify common error codes. Real-time alerts trigger when user-defined quality or network thresholds are exceeded. VNQM monitors Cisco IP SLA and Juniper RPM operations between source and target devices with current and historical QoS metrics. Supported call managers include Cisco Unified Communications Manager, Cisco CallManager Express, and Avaya Communication and Media Server. It runs on the SolarWinds Platform with web and Windows access. The listed plan including VNQM costs $8 per month; VNQM does not support over six million calls monthly.
