Good quality. One had a defect and returned it for another one. Arrived pretty quick.Needed an extra phone for our office. Works great.Great item, fast shipping. Thank youGreat sound quality as we used this phone with Skype. Works like a charm!Great quality and price!Works wellSo, I bought 6 of these phones. An optional accessory is the POWER CORD!!I am using this phone- I have not purchased it through Amazon Though- and it is the best SIP phone in the market. I am both a user and a VoIP provider. Polycom always provides highest quality and I am saying this both from the end user stand point and a provider, who has to deal with configuration and by far there has not been any other brands as user friendly and high quality as Polycom out there. I wish Polycom was offering a current cordless as well!
