Speaking to the press, Mr. Vijay Kulkarni, CEO of the company said, “PacketScanTM is a real-time VoIP analyzer that monitors and captures live voice and video IP traffic with associated call signaling. Hundreds of calls can be monitored in real-time with detailed analysis of selected voice and video streams. Applications include testing of IP voice and video phones, IP / TDM Gateways, IP Routers and Switches, and SIP Proxies. Users can also perform analysis in real-time or on captured calls with various QOS (quality of service) metrics”.
Mr.Kulkarni added, “The new video feature “record and playback video”, allows the user to record audio and video data of a video session to a file in QuickTime format. PacketScan™ can monitor video calls and display both audio and video RTP streams in its summary view. And video calls are separately marked with symbol “V” in the view”.
The voice features of PacketScan™ include live listening, analysis, and recording; power, frequency, and spectral analysis, and tone and digit analysis. Detailed call statistics such as packet loss, gap, jitter, delay, RTP performance statistics, and many other voice band statistics can be monitored simultaneously. Sophisticated filters permit zooming and recording of specific calls of interest. Video sessions can be captured and replayed (in QuickTime *.qt format). And it can collect vital statistics about calls for theoretically an infinite time limited only by the hard disk capacity of the PC or network drive.
