PacketScan™ software supports capturing and decoding of Fax (T.38 data) calls over VoIP. PacketScan™ fax decodes can be viewed in the form of T.38 call graph and call summary with decoded information for all T.38 messages received on the call. The captured fax calls by PacketScan™ can also be analyzed using GLInsight™ by saving the fax calls directly in (*.PCAP) Ethereal file format. T.38 has been enhanced to reassemble the fragmented data and to identify the T.30 message from it. Identified T.30 message is displayed in the T.38 ladder diagram.
PacketScan™ also allows users to extract fax image in the TIFF format from the selected fax call in either GL's proprietary *.HDL file format or in Ethereal *.PCAP file format.
- Real-Time Digit Capturing
Audio Handling Features
- Play to Speaker
Play To Speaker application allows the user to play the RTP streams of a call to the PC speaker using a soundcard. A host of options such as Jitter Buffer settings, As Is, Audio Mixing and so on are available for users to play a live call in real-time or play captured voice files.
- Write To File
Similar to Play to Speaker application, various options are provided for the user to save the captured file in a required format, and use the files with voice quality analysis software to investigate more about the quality of voice in the network. This application write or records the RTP stream to a file in *.wav format. (Examine both directions using Waveform Viewer)
- Save Call
Supports Save Call feature to save successful and failed calls in either in GL’s proprietary *.HDL file format, Ethereal *.PCAP file format, or *.PCAPNG file format. Call Summary details could also be saved for a particular call and this will be saved as a *.rtf file. This allows the users to get data from real-time traffic locations for detailed analysis of a flawed call.
Acts as a Probe in Network Monitoring System
GL's Network Monitoring System uses probes with PDA to prepare and send detail packet statistics, call quality measurements, and Call Data Records (CDRs) to a centralized database. Later these records can be viewed remotely using a web client with graphical and historical reports. For more details, click Packet Monitoring and Surveillance System.

*Note that Video recording is supported only for H263+ codec. However, video QoS statistics is available for all codecs.
H.263 is a video codec designed by the ITU-T as a low-bitrate encoding solution for video capture and videoconferencing. H.263 provides video capture and video conference monitoring capability, while H264 is an industry standard codec for video compression.
QCIF - Quarter Common Intermediate Format, a videoconferencing format that specifies data rates of 30 frames per second (fps), with each frame containing 144 lines and 176 pixels per line.
CIF - A video format used in videoconferencing systems that specifies a data rate of 30 frames per second (fps), with each frame containing 288 lines and 352 pixels per line.
H.264 is the latest video coding standard of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). H.264 is an industry standard for video compression, the codec offers better compression performance over previous standards.
It has demonstrated the significantly improved coding efficiency, lower compressed bit rate for the same image quality, substantially enhanced error robustness, and increased flexibility and scope of applicability relative to its predecessors;
Wide application of H.264 includes;
- Mobile TV broadcasting
- Internet video
- Video conferencing
Support Video QoS for H.263+ and H.264 video codec; Video Statistics such as Source/Destination Video Channels, Media Type, SSRC, Average Delay/Gap, Packet Counts, Codec Type, Missing Packets, Delay, Gap, Video Frame Count, Out Of Sequence count, Duplicate Packets count, Media Delivery Index (MDI- (Delay Factor : Media Loss Rate)), and Frame Rate are provided for each video session. PacketScan™ with Voice, Data, and Video QoS capability addresses customers long felt need of call quality analysis in IP networks.
Media Delivery Index (MDI) measurement is used as a diagnostic tool or as a quality indicator for monitoring a network intended to deliver applications such as streaming media, MPEG video, Voice over IP, or other information sensitive to arrival time and packet loss. Media Delivery Index (MDI) can be used to monitor both the quality of a delivered video stream and to show system margin for IPTV systems by giving an accurate measurement of jitter and delay at network level (Internet Protocol, IP), which are the real causes for quality loss. The Media Delivery Index is typically shown as two numbers separated by a colon the Delay Factor (DF) and the Media Loss Rate (MLR).
Packet Data Analysis is enhanced to display the SIP registration information in tabular as well as graphical format in Registration Summary. This interface displays the SIP registration information in a tabular format which includes user agent, registrar, registered time, status, time to live (TTL), expiry time, remaining time, Registration Request Delay (RRD) and Registration attempts for each user agent. In addition, it displays the active registration graph of the entire registration summary and provides the trace display of each registration.
Include graphs that display the active registration and registration trace message sequences of registered calls at the bottom of the registration summary. The registration statistics display the count of the total, completed, failed, & active registrations along with registration and de-registration packet count.
