Enterprises & 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.

Get detailed documentation for the voice quality of each individual call

Qrystal analyzes all live calls from beginning to end, including all signaling and speech transmission. Data on each individual call is made available in near real-time and is stored for weeks and months. This gives you a continuous and in-depth view into everything that is happening in your VoIP network and its impact on the user experience.

Proactive alarm in case of problems

Proactive operations is high on the agenda of VoIP providers, yet many still rely on their customers to report issues – specifically voice quality. Qrystal warns you of existing or immanent quality degradations in near real-time. Alarms can be triggered for all detected events relating to call control, in-call quality and network performance.

Quickly identify the root causes of problems

Any long call setup time, low MOS or call drop has a reason. Qrystal speeds up troubleshooting by automatically detecting issues and pointing to their root causes. This is particularly useful to quickly isolate the cause of bad user experience to impaired network links, network elements, end devices or your communication service provider.

Pinpoint responsibilities in shared infrastructure and interconnection scenarios

Qrystal continuously monitors network and service performance in different points in the network. This is useful for avoiding and resolving potential blame-games when offering a service over third party networks or when exchanging traffic with interconnection partners. Any issues can be quickly isolated and attributed to the responsible party.

Next-generation KPIs for next-generation voice services

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.
