Voipfuture Qrystal

A very deep and focussed view on voice

Voipfuture’s carrier-grade monitoring solution for voice service providers to control service performance and user experience


Being focused lifts performance to a new level. Our focus is on voice (VoIP QoS). Only. We don't want to monitor everything. We want to be the best at what we do.

More accurate metrics

Sounds easy. But it is not. We break down each stream into snippets. Each of these standardized 5-second snippets contains hundreds of attributes.

Deeper insights

The snippets are standardized building blocks of data, and can be aggregated as required. And sliced for every possible dimension. And automatically correlated with connectivity data to put measurements into context.

Troubleshooting automation

You can sift through Gigabytes of call traces to find the root cause of one-way audio, call drops or metallic speech. Or you can let Qrystal do the work.

Full scalability

Our probes measure what's going on. In large tier 1 networks with millions of concurrent calls. Or in small ones. No limits. What you need is what we measure.
