Qrystal provides communication service providers, wholesalers, enterprises, call centers and cloud-based voice providers with unique, dual visibility monitoring capabilities for analyzing both SIP and RTP packets.
Unlike other solutions, Qrystal provides visibility into both control and media plane. This way, you get the full picture of in-call user experience, all in one place.
Voipfuture’s patented technology automatically identifies typical impairment patterns, allowing you to reduce the time it takes to fix problems.
Qrystal is the only solution to provide actionable timeslice KPIs for assessing in-call user experience. Timeslice KPIs deliver MOS per call, but with all the temporal detail!
Combining voice quality assurance with root cause analysis
Providing deep insights through intelligent packet-by-packet inspection
Enabling effective, automated troubleshooting for both signaling and media issues
Offering accurate voice service intelligence through RTP time slicing
Visibility into call connectivity via SIP signaling monitoring
Data-based insights through 360-degree voice quality information
Visibility into the in-call user experience by monitoring RTP media in detail
Real-time analysis of voice packets on a link is provided by Qrystal Probes. The central Qrystal Manager collects quality information for post-processing, storage and display.
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.
These KPIs are used for:
Qrystal is applicable to all VoIP services, including VoLTE, VoWiFi, IMA, IPX, NGN and enterprise services.
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.
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.
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 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.
Moving voice services to the cloud carries many benefits. However, leveraging these benefits without compromising user experience requires a high level of visibility.
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.

Qrystal is the first and only carrier-grade dual-visibility platform on the market. It provides communication service providers, wholesalers, enterprises, call centers, and cloud-based voice providers with unique, dual visibility monitoring capabilities for analyzing both SIP and RTP packets.
The difference is in detail and focus. Pseudo-information about voice quality is easy to obtain when evaluating RTCP (RFC 3550) reports, which is what many monitoring systems do. However, there are many drawbacks to this approach. RTCP simply does not tell the whole story, if at all.
Qrystal relies solely on information gathered directly from RTP packets of live customer VoIP calls. Thus, trustworthy quality information is always available, regardless of firewalls, customer premises and network equipment. The detailed 5 second measurements also allow applying Voipfuture’s patented pattern matching technology, which helps operations focus on the real problems in a network.
Qrystal is a software solution that runs either on standard COTS hardware or on virtual machines.
No. Qrystal is vendor-agnostic and monitors any standard VoIP traffic.
Qrystal provides full flexibility and can be deployed on-prem, in a private cloud, in the public and in hybrid deployments, e.g., with Qrystal Probes on-premise and the Qrystal Manager in the public cloud. Whatever constellation you choose, all Qrystal components are deployed in infrastructure that is under your control.
Qrystal does not analyze the payload of RTP packets. Network performance analysis is completely independent of the employed codec. Special codec support is only required to assess user experience by computing mean opinion scores (MOS). Qrystal supports all codecs currently in use, from G.711 to EVS and Opus.
Yes. Qrystal is a passive monitoring solution that analyzes the RTP media streams of all actual calls on the monitored links. It analyzes all streams in real-time to produce detailed information for each actual call.
Qrystal is beneficial to many stakeholders within the organization.
It is used by:
technical operation teams—for reporting, alarming and troubleshooting
performance optimization teams—to enhance service quality and user experience
sales and marketing teams who use the unique Qrystal data to attract and retain customers, and
DevOps—as a reliable source of voice service quality data and enabler for Service Automation.
Qrystal is a highly scalable software solution that is already being used by call centers with 500 concurrent call measurements up to Tier-1 carrier networks with millions of concurrent calls.
