This monitoring system uses GL's Wireless, VoIP and TDM probes to capture the voice files in real-time. These files are then transmitted over to GL's Voice band Analyzer, that instantly detects voice files and with appropriate analysis modules, monitors speech levels, noise levels, line echo, and acoustic echo.

Analysis modules such as ITU-T P.561, P.562, P.563, fax and modem analysis, and many others can be hosted as plug-ins. GL's TDM and VoIP probes support all standard protocols, and can perform detailed analysis of voice band streams.

The VBA application can also operate on pre-captured files, making it a near-real time. The analyzer has been designed to work with GL's tools such as PacketScan™, T1/E1 Call Capture and Analysis, and many other recording tools. It supports A-Law, µ-Law, 16-bit linear PCM, and Wave file formats.

VBA works in conjunction with GL's TDM, Packet, and Wireless non-intrusive capture products:

• VBA with GL's TDM T1 / E1 Call Capture and Analysis, or
• VBA with GL's VoIP PacketScan™
• VBA with GL's GSM, CDMA, and 3G Call Capture Products

The essential elements of the TDM and VoIP monitoring systems are:

• VoIP & TDM probes to gather information intrusively and feed it to VBA for analysis
• Voice Band Analyzer to instantly detect the voice file captures and stores the results if necessary
• GL's database stores the real-time and historic data collected by the probes
• GL's web server, which will provide real-time and historic views of the data through various "browser based" clients.
