The Polycom IP 4000 is an excellent conference phone for offices or small to medium sized conference rooms. It delivers exceptional room coverage and has optional expansion microphones for extending the coverage for large conference rooms. Using the standard configuration (without the optional external microphones) the conference phone has a range of about 10 feet. If you attach the external microphone (pack of two microphones) you can extend the range to up to 25 feet from the base station.

They Polycom 4000 is popular among the Asterisk Open Source IP PBX community because it uses the SIP protocol by default.
The Polycom 4000 is very easy to use. There is convenient access to business telephony functions you use most including transfer, hold, redial, and conference with the menu driven use interface, viewable on a high-resolution backlit LCD.
