Overview
This system uses GL's Packet probe called "PacketScan™" and/ or Voice band Analyzer, PacketProbe™ to
monitor packet flows in real-time within a VoIP network. All major VoIP protocols are supported including SIP, H.323,
Megaco, SIGTRAN, RTP, and MGCP. A central database stores the real-time and historic data. The system also facilitates
various views using a web interface known as ‘PacketScanWeb™’.

The essential elements of the Non-Intrusive Packet and VoIP monitoring system are:
- PacketScan™ probe a feature-robust Windows® based software
tool that captures and monitors live IP traffic in a non-intrusive fashion and forwards call detail records (CDRs) as well
as statistics to a central database. PacketScan™ performs detailed analysis of voice band streams gathering QOS
statistics such as MOS (Mean Opinion Score), total packet count, reordered, duplicate and missing packet counts, packet
gap, jitter, and delay. In the VoIP world, it can monitor and measure SIP, H323, Megaco, MGCP, T.38 and video calls. In
addition to quality metrics PacketScan also captures signaling information and sends that to the PacketScanWeb™
database as well.
- PacketProbe™ is a lightweight Linux based tool that only operates on SIP or raw RTP and does not capture or
transmit signaling information
- A central database which will store the data collected by the probes
- A WebServer which will provide real-time and historic views of the data through various "browser based" clients.
- PacketScanWeb™ facilitates result display using a web
interface. With this, one can view real-time
data, navigate through records, filter the collected VoIP traffic summary, and graphically analyze the call volume, MOS,
call completion, failed calls, completed calls, PDD, and so on through a simple web browser.
PacketScan™ Probe Benefits
- Multiple probes at different locations
- Monitors different types of data (Protocols, Codec, QOS Statistics)
- Call Quality Of Service (QOS) for all calls with E-Model based (G.107) Mean Opinion Score (MOS) and R-factor
- All probes are connected to centralized storage location (Database)
- Data processing performed by software only probes
- Allows quick upgrades and modifications
- Utilizes and exploits the power of the latest PC processors (quad-core and beyond)
- Most of the processing (CDR, XDR, Wave file recording, etc) is performed at probe to reduce traffic over
network, redundant local (probe) storage
- Incrementally scalable architecture – ideal for small to large enterprise level deployments
- Fail-safe network taps with bifurcation hardware used to ease data presented to individual probes
- Statistics gathered on all traffic. Call recording (waveform captured) used on trigger-met calls
- Results
- Unlimited recording of signaling and traffic subject to hard disk storage
- A web server for remote access of near real time measurements
- Customizable and detailed report development capability
