Qrystal is a passive VoIP analytics solution for SIP/RTP based voice services, Qrystal Probes sit on the edges of the network and integrate voice quality assurance and root cause analysis.
- Qrystal Probes analyze all voice packets on a link in real-time
- The central Qrystal Manager collects quality information for post-processing, correlation, storage and display
- The data warehouse holds data from billions of calls
- Smart use of standard COTS hardware or virtual infrastructure
In fixed networks the probes are mostly placed around SBCs, routers and media gateways, while VoLTE deployments typically call for monitoring of the S1-U/S11 and/or Mw/Mb interfaces. One probe appliance is typically sufficient to monitor an entire site.
