Press Release : GL Announces Enhanced
Call Management Utility (CMU)

Gaithersburg, Maryland, USA – December 09, 2013- GL Communications Inc announced today its enhanced T1 E1 Voice Call Management Utility software.  A critical feature of the CMU is the ASR Listener, which provides the capability to remotely access recordings in progress (real-time) as well as access to historical recordings.


Speaking to reporters, Mr. Rob Bichefsky, Senior Manager at GL, said, “Managing recorded voice calls is essential especially when recording for extended periods of time. The job of manipulating recorded voice calls is easier when calls can be sorted or filtered by called or calling number, time of day, or length of call.

He added, “GL’s Call Management Utility (CMU), coupled with the GL’s T1 E1 Call Capture and Analysis (CCA) application 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 or E1 lines is completed by the CCA.

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

Mr. Bichefsky further added, “The post processing capability of CMU provides filtering of calls of interest that is recorded calls can be filtered or played back or analyzed as required. All relevant information associated with each recorded call is included e.g. timestamp, direction, timeslot, length of call, size of file, calling #, called #, and voice file name. The user has the option to display all “in-process” calls or a user-defined filtered list of all completed calls.

Also 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.

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.”

  • 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
