Press Release: GL Releases Improved Voice Quality Testing Solutions (VQT)
Gaithersburg, Maryland, USA - June 20, 2008 - GL Communications Inc. announced today the release of
Improved Voice Quality Testing Solutions (VQT) Application. Speaking to the
media, Mr. Rob Bichefsky, Senior Manager of Product Development at GL said, "VQuad™
with Voice Quality Testing (VQT) software provides a single box solution
to automatically establish calls (PSTN, VoIP, Wireless, T1/E1), send/record voice over the established call, and perform
voice quality analysis on the recorded voice files. Up to 8 fully independent tests using different interfaces can be executed
simultaneously." He added, "The system utilizes three widely accepted algorithms in the measurements of voice quality
over all types of networks including Wireless, ATM, VOIP, PSTN, and T1/E1. The algorithms supported by VQT include
Perceptual Evaluation of Speech Quality (PESQ LQ/LQO/WB) per ITU-P.862.1/P.862.2, PAMS per ITU-P.800, and
PSQM/PSQM+ per ITU- P.861."
Mr. Bichefsky further added, "Manual or fully automated measurements are easily conducted. Important features
supported are automated call control, path confirmation, and call progress logging (failed calls, dropped calls...). The
system works as follows: As each voice file is recorded at the destination, the VQT application automatically detects the
completion, transfers the files to where the VQT application (over LAN or WAN) is located, and applies the required
measurement algorithms against the degraded voice files. The measurement results are reported both locally and
remotely through NetViewer™ and / or web based WebViewer™ applications."
