Moving voice services to the cloud carries many benefits. However, leveraging these benefits without compromising user experience requires a high level of visibility.
Qrystal Cloud is a vertical solution that provides crucial data to all stakeholders within a CSP. It is faster and easier to test, set up and operate in the cloud than conventional on-premise solutions. It is applicable to all phases of a CSP’s cloud journey and its accurate service performance data lays the foundation for AI/ML-based service automation in the cloud. Qrystal Cloud has a simple, flexible license model and significantly lower TCO than on-premise solutions.
Qrystal Cloud is the only voice monitoring solution to deliver reliable and actionable user experience data using timeslicing according to ETSI TR 103 639. This provides high temporal detail and the ability to aggregate the data for cells, interconnections and complete services. Qrystal speeds up troubleshooting through behavioral analysis of users and automatic root cause indicators that reduce the time-to-fix by up to 80%.
Leading reasons for call drops are self-learned by Qrystal from observed user behavior. Even better: Qrystal continuously checks all live calls for call drop conditions, not just single test calls.
Transitioning to the Cloud can be a challenge for vendors of network equipment. Cloud-native products are often new developments which may introduce issues that affect user experience. Qrystal provides Cloud infrastructure vendors with valuable insights into their product performance and potential issues. This is beneficial for improving software quality and raising customer satisfaction.

Support for timeslice KPIs (ETSI TR 103639)
Effectively measuring the quality of VoIP services is crucial. ETSI defines proven and accurate time slicing KPIs which complement the well-known and widely used SIP signaling KPIs .
This white paper explains the fixed time slicing technology, which provides MOS and other metrics to accurately assess in-call user experience.
