Businesses are increasingly turning to voice over Internet protocol (VoIP) to improve efficiency while reducing costs. However, with VoIP come associated challenges like security and service assurance. Thus, VoIP monitoring and quality analysis solutions are designed to help address these obstacles.


Telchemy, a provider of VoIP service quality monitoring solutions, recently launched SQprobe 3.0, a new software probe designed for service provider and enterprise telecom services.

The VoIP passive monitoring application is designed to analyze in excess of ten million packets per second of traffic, or 100,000 concurrent VoIP calls. It can retain a small processing time and memory footprint for small form factor and embedded applications requiring capacities of a few thousand packets per second.

Moreover, SQprobe is able to analyze traffic carried over IPv4 and IPv6, supports up to three levels of stacked VLAN, and is capable of analyzing encrypted VoIP streams carried over secure RTP. By taking advantage of mulptiple core systems, the SQprobe analyzes every call attempt and reports on both successful and failed calls. It also reports on a wide range of performance metrics including MOS scores for voice and video, IP performance metrics and signaling performance and call flow. 

For failed calls, SQprobe detects and reports the reason for the failure and provides essential diagnostic data. It can analyze media streams using Telchemy's advanced VQmon technology, which provides more accurate and stable call quality metrics using a unique perceptual analysis algorithm that models the effect of time-varying impairments on user-perceived quality.

Telchemy has led the use of embedded software probe technology and the application of big data and analytics for the VoIP performance management. The company is advancing in the market of voice and video performance monitoring technology for the emerging SDN.

As an embedded probe, SQprobe can be deployed as a VM image or as a native Linux application running within a router, CPE device or data center system. As a dedicated probe, SQprobe can be purchased pre-installed on a hardware appliance or purchased as software to install on an existing server platform. 

By leveraging Telchemy's advanced VQmon technology, SQprobe analyzes media streams. It provides more accurate and stable call quality metrics using a unique perceptual analysis algorithm that models the effect of time-varying impairments on user perceived quality.
