Qrystal Probes

  • Determine the signaling and media stream characteristics at multiple points throughout the network.
  • Inspect all in-memory SIP, RTP and RTCP packets in real time.
  • Generate highly compressed timeslice metrics for further processing by the Qrystal Manager.
  • Analyze call-related SIP signaling at a monitoring point and summarize as xDRs.

Qrystal Manager - a carrier-grade data warehouse

  • Collects all the metric data from the Qrystal Probes for post-processing and aggregation. The data warehouse stores KPIs, CDRs, and other data.
  • A wide-array of analytics and troubleshooting capabilities for effective operations and service monitoring.
  • Numerous interfaces for integration with Operations Support Systems (OSS)/Business Support Systems (BSS) are available out of box.

Patented fixed time-slicing technology

This unique technology creates quality data records (QDRs) which contain highly condensed statistical information for every 5-second segment of an RTP stream. Our QDRs hold several hundred values, ratios, KPIs, and even automatic root cause indicators.

Intuitive, accurate and widely accepted KPIs

These KPIs are used for:

  • Dashboards for NOCs, VoLTE eNB performance monitoring, SLA monitoring, etc. 
  • Adaptive alarming on signaling performance, in-call user experience (MOS) and network performance.
  • Portals and reports for end customers.

Working with Voipfuture is beneficial to all telecommunication players

Qrystal is applicable to all VoIP services, including VoLTE, VoWiFi, IMA, IPX, NGN and enterprise services.

Mobile Networks

Simply using HD codecs is not enough to ensure premium voice quality. This is why Qrystal provides individual cell performance, reasons for call drops and other key data.

Fixed Networks

CSPs can only gain a competitive edge if they maintain excellent voice quality. Qrystal keeps service quality under control while ensuring the efficient use of resources.

Wholesale Networks

 IPX and international wholesale services have undergone profound changes in recent years, making high-quality user experience a must as a key differentiator.

Enterprises and Call Centers

Enterprises and call centers are often faced with the challenge of managing voice services delivered by different providers using one IP infrastructure. This complicates identifying faults and root causes.

Cloud Deployments

Moving voice services to the cloud carries many benefits. However, leveraging these benefits without compromising user experience requires a high level of visibility.

Qrystal Intelligence

A business intelligence solution that provides fascinating insights into your voice service and network. Qrystal’s unique monitoring statistics are processed in the context of your own business rules and then analyzed and visualized interactively for both management and operations.

In addition, Qrystal Intelligence generates intelligent alarms to detect anomalies in network and service performance based on all VoIP traffic flowing through your network.
