Summary: Speakerphone works like a charm in combination with Skype, WebEx and other screen sharing tools. In some cases i have to manually switch the mic/speaker from laptop to speakerphone - not sure if this is a Windows 7 issue or a speakerphone issue.
Summary: Second one I own. Cannot tell if the sound is enhanced for windows 7 as I do not have visibility of the back end configuration. If you want a hands free for communicator then this is an excellent device
Summary: If you use Skype or other VoIP from your computer, this is the best speaker phone. I first purchased 1 at least 5 years ago and it is still going strong. 1 bought a second so I have work and home covered.
Summary: This is a very old design, limited in many ways. It is barely satisfactory if used solely as an individual speakerphone, where the (only) user is right in front of it. However most users tend to use it when they have other participants around the table, almost as if it was a conference room...
Summary: I purchased the Polycom as I work from home and do conference calls via Lync off and on throughout the day. I sometimes find it difficult to hear and difficult to click on the mute/unmute button to speak on calls. This Polycom has solved both of those problems.
