The Konftel 300 is packed with smart features and has been developed for flexible application. You can record your calls onto an SD memory card and the line selector mode allows you to switch between and combine three connectivity technologies, analogue, mobile phone and USB. The conference guide is a useful feature if you make regular calls to the same group as it enables you to set up multiparty calls and save call groups.

The Konftel 300 is also ideal in larger contexts as you have the option of adding expansion microphones, a wireless headset and an existing PA system too. It goes without saying that it delivers ultimate sound quality, based on OmniSound 2.0 , the new generation of Konftel’s crystal clear audio technology.
