Voice Call Management Utility (CMU)



Overview

Managing recorded voice calls is essential especially when recording for extended periods of time. The job of managing recorded voice calls is easier when calls can be sorted or filtered by called or calling number, time of day, or length of call.

GL's Call Management Utility (CMU) application included with GL's T1 E1 Call Capture and Analysis (CCA) provides all the necessary management tools to perform exactly such monitoring functions for ISDN, SS7, and CAS calls over T1 or E1 networks. Call records are immediately generated, indexed, and displayed once a voice recording over T1, E1, or 2-Wire lines is completed by the CCA. The GL’s T1 E1 Analysis boards allow easy bridging/monitoring connections to a T1 E1 interfaces. By tapping T1 E1 lines, Call Capture and Analysis (CCA) captures SS7, ISDN, and CAS calls on East, West, or both the directions simultaneously.

The GL T1/E1 Analysis boards allow easy bridging/monitoring connections to a T1 E1 interfaces. By tapping T1 E1 lines, Call Capture and Analysis (CCA) captures SS7, ISDN, and CAS calls on East, West, or both the directions simultaneously.The CMU then can be used to pull all the voice files in real-time from the user-defined capture directory of CCA for generating the call records.

Recorded calls can be further filtered or played back or analyzed as required. All relevant information associated with each recorded call is included such as, timestamp, timeslot, length of call, and the size of voice file. The user may configure a different filters for each monitoring instance. The user also have the option to display all Completed Calls, Active Calls (shows real-time capturing information), or a user-defined filtered list of all Completed Calls.

The most important feature of CMU is the ASR Listener, which provides the capability to remotely access the recording in progress (real-time) from multiple T1E1 probes. As indicated in the block diagram above, CMU can work with multiple GL's T1E1 CCA probes using ASR listener to monitor call recording remotely.

Using the CMU post-processing feature, the user has the fundamental capability to play each voice file. Audio playback of completed and captured calls allows a captured call to be instantly played to the PC speakers, either in the East direction, or the West direction, or both directions simultaneously. The audio files can also be analyzed using a waveform viewer for further troubleshooting.

Main Features

  • Complete call records for each captured file.
  • Filter/Search for specific calls.
  • Post process capability to view the directory of captured files, log files and instances.
  • Streaming audio files over TCP/IP and playback voice on either East, West, or both the directions simultaneously.
  • Real-time voice playback (during active call) and post-processing voice playback (after call is completed).
  • Statistics for all call records.
  • Works as  complete automated T1 and E1 voice logger

Filters

The CMU provides the mechanism to easily view an entire directory of captured voice files. These voice files include any type of traffic, including full duplex conversations, when used in conjunction with the GL T1/E1 Analysis Call Capture and Analysis application. As a fundamental capability within the Call Management Utility, the user can easily configure filtering for real-time call record capture as well as post-processing display. During real-time processing, the user may configure a different filter for each monitoring instance, and hence providing added flexibility.

Post Processing Capability

The CMU's Post Processing capability allows the user to import a previously saved log file, or an instance, or the captured files from the call capture directory. When importing, the user has the option of adding a filter to the search criteria. Thus, the user may import all voice files or import only those that adhere to the search criteria. Any call can be viewed, played if the captured file still exists in the call capture directory, and can be edited.

The CMU will automatically sort and display all call records and produce the statistics associated with these imported voice files.

A call that is currently active (real-time) or a completed call (post processing) can instantly be played to the PC speakers, either the East, West, or both directions simultaneously. The voice files need not be co-located on the same PC as the Call Management Utility. The Call Management Utility can automatically stream the audio over the established TCP/IP connection with the help of the listner. The user may also display the captured call to a waveform viewer for further analysis.

Using the Call Management Utility post-processing feature, one can display call records associated with a directory of recently captured voice files. Searching and filtering on all available information (called number, calling number, timestamp, length of call) can easily be done with the Call Management Utility, results displayed to a separate screen. Individual call records are displayed for each file and the user has the same fundamental capability to play each voice file.

Any call can be viewed, played, and even edited. Shown below is a captured call with both directions shown.

Statistics

The CMU will automatically sort and display all call records and produce the statistics associated with the voice files. Statistics of the calls such as record number, size of the call, and length of the call can be obtained for the all completed and filtered calls.

Custom statistics can also be obtained for the specific calls across multiple instances based on the timestamp, direction, timeslots, length of call, size of file, calling #, called #, crv, and voice file name.
