Polycom has been known for the conference room solutions for years, but as telecom has moved more towards a universal or interchangeable, non-proprietary phones, they have been the market leader in VoIP phones. They have a rock solid product, they invented HDvoice, and brought their speakerphone quality from the conference rooms to your desktop. Many Polycom models are available, ranging from entry level (one line, monochrome display, 10/100 connection) to full executive models (6 lines, color screen, touch interface). Video phones are also making their way into mainstream.
