CDR Report Generation

PacketScan™ can generate PDF reports summarizing all calls or a certain subset of the calls captured. The PDA Summary View can also export all terminated call details as a text file (CSV format) during the live capture. This feature requires activating the Export Terminated Calls option from PDA prior to live capturing. This structured text file can be imported into Excel® using a custom add-in (Excel-Dashboard-Tool-IP.xlsm) to generate different chart types such as call volumes, call duration, call failure causes, CMOS, LMOS, packet loss and more.

For more details, refer CDR Analysis Tools webpage.

Performance Metrics

• Call Summary displays signaling, audio, and video QoS parameters for each call.
  
  Signaling parameters include Caller & Callee id information, call duration, session information (Establishment Ratio, Establishment Effective Ratio, Session Defects, Ineffective Session Attempts, Completion Ratio, Request delay, Post Pickup Delay), and so on.
  
  Audio parameters include media type, packet count, jitter, delay, gap, MOS, R-factor, lost packets, and so on.
  
  Video QoS parameters such as Video Channels, Codec Info, SSRC, Frame Count, Packet Count, Packets Lost, Frame Rate, Media Delivery Index (Delay Factor : Media Loss Rate), Average Media Delivery Index are calculated for all video calls
• Detailed statistical information are provided for Inband (DTMF & MF )events, RFC 2833 events, RTP/RTCP packet count and reports per direction, Duplicate and Missing Packets

Call Summary - Signaling, Audio, and Video Parameters

• Calculates minimum, maximum, and average Round Trip Delay (RTD) values for SIP calls
• Call Quality Of Service (QoS) for all calls with E-Model based (G.107) Mean Opinion Score (MOS) and R-factor with individual and summary statistics presented in graphical and tabular formats

Triggers and Action Feature

Traffic Handling Features (Fax, Digits)

• T.38 fax calls
  
  

  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
  
  

  PacketScan™ provides a means for digit examination and capturing. An easy-to-read window indicates the direction of the captured digits along with the duration, power and frequencies. DTMF, MF and User-defined digits/tones are fully supported.

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.

  
  Play Jitter Options

• Write To File

  Various options are provided to save captured calls and use the files with voice quality analysis software to calculate the mean opinion score of the call. This application writes the RTP stream to a file in *.wav format.

  
  Write to File

• 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.

Video Quality Metrics

Support 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).

Registration Summary

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.

Registration Summary

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.
