Bought these 10 years ago. Used them for 3 years before we downsized. Been sitting in a box for 7 years. They were top of the line at the time.

There are 9 desk phones (Polycom Soundpoint IP 550) and 1 conference phone (Polycom Soundpoint IP 5000)

Great sound quality and reliable workhorses. Just plug in, register with your VoIP provider and use like a regular phone.

Handles 4 different lines.
Full duplex speaker phone
Only requires one internet access point, you can plug your computer into the phone
