Acoustic Echo Cancellation in IP Phones
Overview As voice over IP (VoIP) is emerging as a viable alternative to PSTN the performance of VoIP devices is expected to match that of traditional PSTN equipment. Global IP Sound selected five commercially available hands-free-capable IP phones to perform a series of subjective evaluations of the overall and specific aspects of quality related to acoustic echo cancellation. The goal was to evaluate the performance and quality of acoustic echo cancellation in currently available IP phones made by major vendors and to determine whether major brand VoIP phone could perform as well as typical PSTN speakerphones.
