QUEBEC CITY – EXFO Inc. has added Perceptual Objective Listening Quality Assessment (POLQA), the newest voice quality measurement technique standardized in P.863 by the ITU-T, to its BrixCall product line.
With voice-over-LTE (VoLTE) entering commercial deployment phase, EXFO said that service providers are looking to capitalize on premium services such as high-definition (HD) voice, and will need to ensure that high fidelity impairment-free voice is actually being delivered. POLQA allows for true customer experience analysis of HD voice services, providing superior measurement of common voice and HD voice quality impairments such as loss of fidelity, speech clipping, unacceptable noise levels, transcoding errors, excess latency and echo.
"By leveraging POLQA to validate end-to-end call quality, service providers are assured that their new HD voice services are delivering the enhanced quality that's expected," said Claudio Mazzuca, VP of systems and service assurance division, in the news release. "The introduction of POLQA-in addition to our recently announced availability of VoLTE/IMS monitoring and troubleshooting functionalities such as live VoLTE traffic generation and the direct performance monitoring of critical IMS core elements-asserts EXFO's leadership in VoLTE testing and service assurance, and gives our BrixCall product line a further edge for present and near-future network deployments."
