What SolarWinds VoIP & Network Quality Manager is
SolarWinds VoIP & Network Quality Manager (VNQM) monitors VoIP call quality and WAN performance for network administrators. It tracks jitter, latency, packet loss, round-trip time, and mean opinion score, and supports synthetic call tests and SIP trunk monitoring. Call detail and call management records help locate affected calls and inspect call paths, quality measures, and common error codes. Users can set thresholds for real-time alerts about call quality or network performance. For WAN monitoring, VNQM tracks Cisco IP SLA and Juniper RPM operations between source and target devices, with real-time and historical QoS metrics. Supported call managers include Cisco Unified Communications Manager, Cisco CallManager Express, and Avaya Communication and Media Server. VNQM runs on the SolarWinds Platform as a self-hosted product, with web and Windows platforms listed. SolarWinds includes it in the Observability Self-Hosted plan, listed at $8 a month per node; VNQM is not priced separately on the pricing page. The product does not support more than six million calls per month.
