Tried and tested

The Konftel 300IP is a big favorite with companies and organizations around the world. This is due to the winning combination of product quality, practical features and design. As a SIP telephone, it has been tested and validated for a wide range of popular IP platforms (see interoperability table), in accordance with Konftel's strategy.

Smart features

This is a proper conference telephone. The built-in bridging function handles five-way calls, which reduces the need for external bridging services. The conference guide makes it easy to call up groups at the touch of a button.
Another popular feature of the Konftel 300IP is recording onto an SD memory card.

Grows with the task

The Konftel 300IP fits everything from small rooms to large auditoriums. It includes the option to connect a pair of expansion microphones to increase the room pickup range. You can also connect a wireless headset if you're lecturing. If you use the PA interface box to connect to a PA system, there is no limit to the size of the meeting room.


Even the smallest noise can be a real distraction

That's why we've spent more than 30 years honing our OmniSound® audio technology. Perfection every time.
