Qrystal is a carrier-grade voice monitoring solution that ensures premium call quality. It provides unmatched visibility into both signaling and media quality, delivering actionable insights on user experience and network performance through patented time-slicing technology
Overview
Qrystal helps you maintain full control of voice service quality when moving to the cloud. It analyzes all VoIP traffic packet-by-packet, automatically detects root causes of issues like dropped calls, and shortens troubleshooting time by up to 80%.

Qrystal is the only VoIP monitoring solution with integrated control and media plane analytics, providing a complete end-to-end view of your voice service performance. While moving voice services to the cloud offers tremendous benefits, the transition process introduces a critical trade-off between cloud flexibility and service visibility.

- Automatically identifies problems such as dropped or silent calls
- Provides accurate and fast root cause analysis
- Aggregates data to provide valuable statistics and KPIs
- Assures high user experience that meets all user expectations Qrystal's patented time-slicing technology, conforming to ETSI TR 103 639 standards, delivers high temporal detail that genuinely represents end-user experience. This allows you to maintain control of your voice service quality while enjoying all the benefits AWS has to offer. Qrystal is easily deployed according to your requirements, whether fully cloud-based, hybrid, or as a managed service. Its flexible architecture supports small deployments up to large-scale tier-1 carrier implementations, with costs that scale with your needs. Use Qrystal to deliver significant business outcomes, including up to 96% decrease in dropped and silent calls, 80% shorter time-to-fix for issues, and comprehensive visibility into service quality that ensures your customers receive the premium voice experience they demand.
