Press Release: GL Enhances PacketScan™ with Unique Triggering and Search Capabilities For "Calls of Interest"

Gaithersburg, Maryland, USA - January 25, 2012 - GL Communications Inc. announced today the release of its enhanced PacketScan™ software with Unique Triggering and Search Capabilities For “Calls of Interest”.

Speaking to reporters, Mr. Karthik Ramalingam Product Development Manager said, “Quality of VoIP service has always been a concern for carriers and service providers who know that being proactive in monitoring voice quality means keeping customers happy. There are free applications such as Wireshark that can be used to capture and listen to u-law and A-law calls. It can also be used to view reports of packet conditions such as packet loss and jitter that degrade quality. While powerful, Wireshark has limitations when being used for general quality monitoring compared to GL’s PacketScan™. Multiple PacketScan™s can be integrated with a centrally connected PacketScanWeb™. QoS parameters like MOS/R-Factor for voice calls, Media Delivery Index (Delay Factor: Media Loss Rate) for video calls and SIP Performance Metrics can be obtained. Triggers and Actions feature helps to analyze calls of interest. Also wide range of codecs are supported such as AMR, AMR-WB, EVRC and more.”

He added, “Inherently, PacketScan™ is a powerful tool that features real-time capture and monitoring of IP traffic, segregation and capture of VoIP calls (H323, SIP, MGCP, Megaco, T.38, and others), and collection of statistics about calls. It features rich graphics, ladder diagrams, CDRs (Call Data Records), and almost every CODEC. The application allows the user to perform a host of activities on the monitored calls allowing one to get an exact picture of QOS (quality of service) and adherence to protocol standards for the system under test or observation. It can also monitor, report, analyze, and capture calls for infinite time, limited only by the finite space of your hard disk or network hard drive!.”

Mr. Ramalingam further added, “PacketScan™ has been enhanced to work with GL's VoiceBand Analyzer (VBA) and Call Data Records (CDR) applications to trigger on all calls and generate comprehensive call detail reports along with audio files. PacketScan™ can also be used as a stand-alone tool as well as a probe in a distributed system using a central database such as Oracle as implemented in PacketScanWeb™, a central monitoring system for a comprehensive view of network performance."

Important Enhancements

  • Search for “Calls of Interest” - To provide a more comprehensive method for analyzing pinpointing quality problems, PacketScan™ has been enhanced to work with GL’s VoiceBand Analyzer (VBA) and Call Data Records (CDR) applications to trigger on all calls and generate comprehensive call detail reports along with audio files. The audio files are processed using VBA to measure actual analog voice parameters such as Active Speech Level (ASL), Noise Level, Activity Factor (AF), and RMS power. CDR application uses the per call data from PacketScan™ and VBA analytics to provide useful call detail records for further analysis using Excel®.

  • PacketScan™s powerful Triggers and Action feature now includes options to save a set of Call Detail Records for each call containing the signaling, RTP packet statistics, and Mean Opinion Score (MOS) / R-factor scores along with the actual recorded audio file of the call for complete and comprehensive analysis of troubled calls.

  • The generated CSV reports from CDR application are analyzed using built in tools included with Excel. The records can be filtered using Advanced Filter in Excel® tool based on signaling, or various measurements to generate reports of “calls of interest”. The voice files of these calls can be either downloaded, or played back using Goldwave® or any audio program.

  • PacketScan™ can now be configured to automatically start monitoring traffic with filters, trigger actions, and parameters previously saved. This also includes automatically connecting to a remote database for PacketScanWeb™ applications. This can be useful in remote monitoring applications where a laptop can be setup and configured for plug-n-play testing.
