SolarWinds VoIP & Network Quality Manager
Austin, Texas, USA
What it 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 administrators locate affected calls and examine call paths, quality metrics and common error codes. VNQM can issue real-time alerts when call quality or network performance passes thresholds users define. For WAN monitoring, it 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. The product runs on the SolarWinds Platform as self-hosted software; integration with Network Performance Monitor can provide additional device metrics. The plan that includes VNQM is listed at $8 per node per month, billed annually for multi-year contracts; volume discounts are available, and VNQM is not separately priced on the pricing page. SolarWinds says it does not support more than six million calls per month.
