Voipfuture is the only monitoring vendor fully focused on voice service monitoring. Voipfuture’s flagship product Qrystal covers all aspects of voice monitoring, including availability, call management, and in-call quality. It delivers accurate data on any standards-based voice service. This data enables efficient operations based on deep analysis of SIP and RTP traffic and even auto-detection of impairments such as dropped and silent calls. It supports performance optimization through data aggregation for routes, and destinations enabling trending, alarming, and benchmarking.

While the probing software is open source, the frontend is commercial software. VoIPMonitor analyses the quality of VoIP calls based on network parameters, namely packet delay variation and loss. MOS is estimated according to the ITU-T G.107 E-model, however without taking the actual codec into account. Monitoring data is stored in a MySQL or ODBC database. Optionally, each call can be stored in a pcap file allowing to decode the audio and play it back via the commercial user interface. VoIPMonitor natively only supports G.711 codecs, but commercial plugins provide support for some other codecs used by fixed-line VoIP services.
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.
