Update by user Aug 31, 2020 Contacted dozens of times with no good results. Employees just don't care about Support and Customer Service. Employees just don't know their product so they give incorrect info and even their website has incorrect info on their products. Original review posted by user Aug 31, 2020 POLYCOM MAY HAVE GREAT PRODUCTS BUT HAS THE WORST SUPPORT AND SALES PEOPLE! WITHOUT GOOD SUPPORT AND SALES PEOPLE A GREAT PRODUCT IS WORTHLESS!!! Their Customer Support and Sales People give incorrect info and their website has incorrect info about their products. One would think the manufacture would have the correct info about their products! User's recommendation: Use a Voip supplier!
