GL’s 2-Wire Solutions for IVR and VM Testing

Gaithersburg, Maryland, USA – Mar 11, 2020 - GL Communications Inc., a global leader in telecom test and measurement solutions, addressed the press regarding their 2-Wire test solution for IVR and VM testing.

“Testing Interactive Voice Response (IVR) along with Voice Mail (VM) functionality and quality is crucial for any carrier or industry using such supporting methods for customer response. In addition, as the 2-wire Analog Audio moves toward High Definition (HD), testing for Voice Quality becomes crucial when connected through an ATA or Gateway to the home”, said Robert Bichefsky, Director of Engineering at GL Communications Inc.

GL provides the complete automated solution for testing 2-wire and 4-Wire Narrowband and Wideband (HD Voice) through physical Analog interfaces using GL's VQuad™ and Dual UTA HD Hardware.

He further added, “VQuad™ with Dual UTA HD provides a complete automated network testing solution. This includes 2-wire HD Analog FXO interfaces (RJ-11) which, when coupled with the GL Voice Quality software using the POLQA algorithm (per ITU-P.863), provides the necessary voice quality measurement and analysis tools”.

When traversing the IVR or VM service confirming prompts as well as the deposited message within VM is crucial. Using the GL Speech to Text Conversion utility with automated analysis of the converted speech can fully support this requirement while executing within the VQuad™ scripting.

GL's VQuad™ mTOP™ Rackmount, a high-density form factor solution which includes one or two 1U rack units per VQuad™ system housing multiple Dual UTA HD hardware units, can be used for high density testing. This solution can be scaled up to support 12 telephony devices per system while adding additional remote systems to achieve much higher densities. If low density is required, the mTOP™ Probe all-in-one unit can support 2 telephony devices in a portable solution.
