Press Release : GL Announces Traffic Analysis Tool for Voice Over IP

Gaithersburg, Maryland, USA – February 06, 2013- GL Communications Inc announced today its enhanced Traffic Analysis Tool for Voice over IP called Packet Data Analysis (PDA).


Speaking to reporters, Mr. Karthik Ramalingam, Manager Product Development of the company said, “GL’s Packet Data Analysis (PDA) is an outstanding too for live monitoring of signaling and traffic over IP. Packet Data Analysis (PDA) is distributed with GL’s Packet Analyzers, allowing users to monitor live IP networks including capture, analysis, and reporting of every call in detail. Supported protocols include SIP, MEGACO, MGCP, H.323, SCCP, RANAP (UMTS IuCS), and GSM A.

GL’s Packet Analyzers can capture IP packets over different transmission lines, including - IP, T1, E1, T3, E3, and OC-3 STM-1 / OC-12 STM-4. PDA then processes the captured packets, identifies, and segregates calls based on signaling and traffic parameters.

He added, “Users can listen/record audio and video data of calls in real-time; perform power, frequency, spectral, tones, digits, and video analysis with ease and precision; get an exact picture of QOS (quality of service) and the technical adherence of the system under test (adherence to the protocols specified by the standardizing authority).”

Mr. Ramalingam further added, “Detailed call statistics include packet loss, gap, jitter, delay, RTP performance statistics, R-factor & MOS scores, and unparalleled voice band statistics. Sophisticated filters permit zooming and recording of specific calls of interest. All or filtered traffic can be recorded into a trace file.”
