VoIP Analytics
Scalable real-time visibility of VoIP performance.
Corvil passively taps into the packet data flowing in the network and automatically discovers all VoIP calls, tracks the lifecycle of the call and reports the key performance metrics in real-time.
Unparalleled Scale
Corvil 10000 can monitor 100G networks and analyze up to 20,000 concurrent calls per appliance.
Open APIs
Extensive open APIs and live streaming of key metrics to Splunk, Nagios, Orion, and other third-party operations management solutions.
Vendor Agnostic
Corvil can work with any VoIP system, regardless of the manufacturer and allows organizations to easily integrate into their existing infrastructure.
Report the real user experience for every VoIP call in real-time with one-click access to the underlying VoIP signalling and media packets to quickly troubleshoot user complaints.
Challenge
Ensuring high-quality voice communication is essential for any business, but managing VoIP infrastructure can be a complex and challenging task. VoIP issues are highly visible and can severely impact the day-to-day operations of an organization.
Large organizations often have complex and distributed VoIP infrastructures, and audio quality is extremely sensitive to latency. Call setup issues can occur at multiple stages in the signaling path and can be caused by interoperability problems between vendors, configuration issues, or overloaded servers. Additionally, VoIP must compete with other network traffic, which can adversely affect voice signaling and call quality.
It can be difficult for organizations to justify the cost of a standalone tool for VoIP, as it is just one of many critical services. Current products may not be able to scale to report the real user experience for every VoIP call. Additionally, service provider WAN performance can impact VoIP quality, but latency, jitter, and loss for user calls are not always measured.
Outcomes
Improved audio quality and reliability for all users across the VoIP estate
Proactive problem identification with live production dashboards and alerts
Increased operational efficiency with call-oriented workflows
Cost-effective and flexible with options for full analytics and pure packet capture for 20,000 concurrent calls
Hold vendors accountable by reporting latency, jitter, and loss with packet captures as a source of truth
SOLUTION
The Corvil Analytics solution uniquely mines the packet data flowing in the network by automatically discovering all VoIP calls, tracking the lifecycle of the call and reporting the key performance metrics in real time. Corvil provides real-time reporting and troubleshooting of performance issues for VoIP services. This includes tracking the full lifecycle of every call from setup to teardown and reporting on real user experience based on MOS scores derived from actual RTP traffic seen on the network. MOS scores are reported based on jitter and loss measurements of 100% of RTP media traffic for up to 20,000 concurrent calls in a single appliance.
