Tolly Enterprises, an independent technology testing service, conducted a comprehensive study comparing the voice quality and features of Avaya B100 conference room phones to similar phones manufactured by Polycom.
Thirty-six office workers were asked to rate the phones on call clarity and available features while situated in a specially engineered office environment. The specific units evaluated were the Avaya B149, Avaya B159 and Avaya B179. The results of this study showed that the Avaya phones performed at a higher level than Polycom and offered additional features. Call recording is a very desirable feature on a conference phone and is only available on the Avaya models. The entire study is attached at a link below.
