Update by user Jun 02, 2019 Poly must realize that its greed is bad for it and replace my U.S. wall module with a European or Universal one without further delay. Original review posted by user May 29, 2019 I have been a loyal Polycom and Plantronics customer for twenty years, buying thousands of dollars’ worth of products from them. I live outside the U.S. and, due to electrical power differences, some of their telephone accessories, such as power supplies, need local versions. Polycom has joined with Plantronics to form Poly. Their products are the most expensive in their market. Whenever I need to exchange a power supply or wall module for my phones they refer me to their Sales to buy another product. My messages to Poly’s “leadership,” including their CEO Joe Burton, have been ignored. They don’t seem to care about your satisfaction, unless you are a big business that gives them hundreds of thousands of dollars in revenue.
