PacketScan™ - SIP / H323 / Megaco / MGCP / RTP / RTCP / Video Analysis


With most carriers rolling out multi-services, including voice, video, fax, and data transported via packet networks, there is need for constant testing and monitoring of Quality of Service (QoS) and Network Performance of Next Generation Networks (NGN).

GL's PacketScan™ - an All-IP Network Monitoring software offers powerful features to capture and monitor live signaling and traffic over IP (version 4 and 6).

The PacketScan™ is available in the following flavours -

  • Basic PacketScan™ (PKV100) software
  • PacketScan™ High Density (HD) IP Traffic Analyzer w/ 4x1GigE (PKV120) – includes PKV100 – Online (not Offline) for temporary audio codec support
  • PacketScan™ High Density (HD) Network Monitoring Appliance 
    w/ 2x10GigE (PKV122) – includes PKV100 – Online (not Offline) for temporary audio codec support

It captures, segregates, monitors and collects statistics on all IP calls. Almost all VoIP and Wireless protocols over IP transport layer, as listed below, can be captured and decoded for troubleshooting network problems.

GL’s PacketScan™ HD is a high density multi-protocol 1U rack mounted network monitoring appliance that can capture and process analysis of vast array of communication protocols covering IP and Wireless networks.

For more details, visit PacketScan™ HD – Network Monitoring Appliance. 

Some of the important applications of PacketScan™ are:

  • Supports decoding of almost all industry standard signaling protocols – See Protocol List for more details.

  • All traffic supported – Digits, Tones, Voice, Video, Fax Live monitoring Ipv4 and IPv6 (version 4 and version 6) networks
  • SIP ED137B for Air Traffic Monitoring (Air-to-Ground, and Ground-to-Ground)
  • Segregates, captures, and collects statistics on VoIP and Wireless calls 
  • Monitors QoS (quality of service) on voice and video calls
  • Permits analysis of adherence to protocol standards for the system under test or observation
  • Provides graphical presentation of analysisincluding ladder diagrams of protocols
  • PacketScan™ can be run on any PC with Windows® 7/8 32 bit and 64 bit OS, an Ethernet card and a sound card. All the features can be accessed through a user friendly GUI.

Thousands of calls can be monitored in real-time including detailed analysis of selected voice band streams. Applications include testing of IP phones, Gateways, IP Routers and Switches, and Proxies.

Users can listen/record audio and video data of a session in real-time; perform power, frequency, spectral, tone and digit analysis, and video analysis with ease and precision; get an exact picture of QoS (quality of the service).

Its ability to monitor / record audio and video data of a session to files (in QuickTime *.qt format), allows user to perform powerful video analysis. The captured VoIP calls can play-back video using 3rd party VLC Viewer application. The application is capable of displaying Video Statistics such as Source/Destination Video Channels, Media Type, SSRC, Total Packet Counts, Missing Packets, Duplicate Packets and Out of sequence Packets, Average Delay/Gap, Video Frame Count, Frame rate, Media Delivery Index (MDI- (Delay Factor: Media Loss Rate)), and Average MDI for each video session.

PacketScan™ with Video QoS capability addresses customers long felt need of Video Call Quality in IP networks.

Detailed call statistics such as packet loss, gap, jitter, delay, RTP performance statistics, R-factor & MOS scores, and unparalleled voice band statistics can be monitored simultaneously. Sophisticated filters permit zooming and recording of specific calls of interest.

PacketScan™ supports Packet Data Analysis (PDA) module allowing users to report every call in detail. PDA processes the captured packets, identifies, and segregates calls based on signaling and traffic parameters. Supported protocols include SIP, MEGACO, MGCP, H.323, SCCP, RANAP (UMTS IuCS), and GSM A.

PacketScan™ further supports the following three views in Traffic Analysis or Packet Data Analysis (PDA) window:

  • Summary View (Call Quality Matrix) displays complete summary of call information in graphical format along with a summary of alerts.
  • Detail View (RTP Diagnostic View) displays packet by packet statistics for particular call information in tabular format

These interfaces allow users to define parameters such as E-Model based MOS and R-Factor score, VQMon settings, & Dynamic Payload Mapping. It also supports real-time digit capturing like DTMF, MF and user-defined digits/tones.

  • Registration Summary View displays statistics and status of the SIP registration process, an active registration graph, and registration trace graph of each SIP registration.

What sets apart PacketScan™ is its ability to collect vital statistics about calls for theoretically infinite time. The ability of PacketScan™ to capture data is limited only by the hard disk capacity of the PC. It can work withNetSurveyorWeb™, a central monitoring system for a comprehensive view of network performance. It features rich graphics, ladder diagrams and CDRs (Call Detail Records).
