number of GL's PacketScan probes and/or GL's PacketProbes are deployed in remote locations across the network to passively monitor VoIP traffic. Whenever a monitored call completes, the scan/probe calculates a variety of quality metrics (MOS, loss, delay, jitter, etc) and sends the metrics to the central Oracle database for storage. This data can then be accessed in real time from anywhere in the world through any standard web browser. In addition to viewing real time data, PacketScanWeb can also custom filter historical data and generate various reports and graphs that summarize overall network health.”
He added, “PacketScan is a powerful software tool that captures and monitors live IP (version 4 and 6), VOIP and IP based Video traffic. It segregates, captures, monitors and collects statistics on VOIP calls:SIP, H323, MEGACO, MGCP, T.38 and video calls. In addition to calculating call quality metrics like MOS, R - Factor and so on, PacketScan also captures signaling information and sends that to the PacketScanWeb database. PacketProbe is a lightweight Linux based tool that only operates on SIP or raw RTP.”
Mr. Kulkarni further added, “The key benefits of PacketScanWeb are its ability to identify and analyze network trends using Key Performance Indicators and automatically alert users when Calls of Interest occur. And helps in customized filtering for fraud detection, quality of service monitoring, and protocol error indications and also provide comprehensive analysis from overall network health to detailed protocol monitoring. And also provides a feature for flexible report generation.”
Important New Features for PacketScanWeb:
-Customize Filters: User can filter calls based on parameters such as MOS and R-Factor to learn the voice quality, and also can filter different VOIP calls based on Protocol Type:1 for SIP, 7 for H323 and 3 for RTP and other parameters like Called/Calling Number, Probe, Payload, Duration etc.
-Apply single or multiple filters for data analysis; use logical operators between filters
-Set alarm conditions and generate alerts of different types like email alert, visual alert, audible alert, or even log into tables for future analysis.
-Ability to send email alerts on scheduled time based on user - defined alarm conditions
-Ability to customize column views with sorting capabilities for call detail records.
-Navigate through records, and filter the collected traffic summary
-Easy navigation of records to display Previous or Next Hour, Day, Month, Year through navigation tool
-Reports are displayed both in tabular and graphical formats; customize reports and graphs based on SQL queries.
-Graphs provided for Answered calls Vs Failed calls, Call duration, MOS score (conversational and listening), Average Packet Loss, Call Failure Cause (i,e Unknown number, Busy, Unanswered, Client Errors, Server Errors, Global Errors), Session Request Delay for successful and unsuccessful calls with an option to switch between Bar or Pie chart.
-Ability to filter and view the records in CDR from graphical reports by just clicking on links provided
-Ability to export generated graphical and tabular reports to PDF file
-Export the call detail records - Ability to export CDR displayed based on time filter or record index as PDF.
