Newsletter: GL's VoIP Call Generation and Analysis with Packet Series Product Line

Welcome to the September Issue of GL Communication's Newsletter providing information and insight into the latest product introductions and reviews.

Voice Over Internet Protocol (VoIP) systems are expanding at a dramatic pace. It's predicted that 75 percent of all voice traffic will be carried over VoIP networks by the year 2007. To meet this trend with robust test and measurement equipment, GL recently announced the release of their Packet Series products, PacketGen™ and PacketScan™. These products provide SIP call generation and SIP/RTP/RTCP analysis. PacketGen™ and PacketScan™ products are ideally suited for simulation and analysis of VoIP Networks, Gateways, Routers, Proxies and Switches. These tools are intuitive and easy to use.

The Packet Series products are software based and can reside on any Windows PC, including desktops and laptops, making them one of the most versatile VoIP testing products available in the market. They build-on and extend GL's analysis and simulation strengths from the TDM world to the VoIP world.

PacketGen™ provides call simulation over VoIP systems through a unique distributed architecture. It can generate thousands of calls, providing vigorous stress tests of VoIP networks. Call density can be gracefully increased by adding SIP/RTP cores, while maintaining control through a single remote User Interface, thus controlling all systems simultaneously. Real-time voice, fax, tones, digits and noise can be generated using an optional RTP resource board. PacketGen™ also provides statistics, call records and quality of service (QOS) measurements. The QOS is provided using GL 's VQT product to simultaneously generate PAMS, PSQM, and PESQ MOS scores.

PacketScan™ provides real-time audio monitoring, analysis and statistics on both SIP and RTP/RTCP messages. Detailed call statistics, call trace, RTP performance statistics, and voiceband statistics can be viewed simultaneously. Capability is provided to listen to the RTP audio traffic either in real-time (as and when call occurs), or in post processing (after the call is complete). Perform power, frequency, spectral, tone and digit analysis with ease and precision. Sophisticated filtering of the real-time data and statistics is provided via user-friendly screens.

An application note has been provided describing the GL's Packet Series in detail. Please review this application note and give us a call if you are interested in GL's products/software for this or other applications. We would be happy to consult with you on solutions to your testing needs and we look forward to hearing from you.
