The Konftel 55 series

The Konftel 55 and the Konftel 55W form a series of simple-to-use, versatile conference devices delivering impressive, crystal-clear sound thanks to the patented OmniSound® HD audio technology.

The Konftel 55 series has been specially designed to be the hub of your communications. Connect your computer, cellular phone/tablet and deskphone for effortless meetings with superior audio quality whatever the communication tools. Moreover, VoIP calls can be bridged with calls via a desktop or cellular phone. Switch easily on the smart LCD color screen that only displays the current connections.

The Konftel 55 series has recording capability. Calls and dictations recorded on the memory card can be played back, saved or shared. These highly portable units look just as good on the desktop and in the home office as in the conference room. The difference between the models is that the Konftel 55W has Bluetooth and is equipped to accept expansion microphones. It’s up to you to choose your favorite.

UC Integration

The use of UC applications for communicating and collaborating in real-time from the PC is growing. The Konftel 55 series facilitates that through smart feature layers in the conferences devices software. The solution makes call functions in the UC client available directly on the touch screens of the Konftel 55 and 55W.
