Use the device as a supplement to a Optiset60 to the conference table to hold teleconferences can. The works! Perfectly: After having once paired, you have to turn on only the box, and you end up all calls on the box (there is ringing it and man can take over with the play button) or handled by the Box, if one chooses himself. These good sound and very good range of the microphone. All participants are well understood, without having to bend right in front of the box. I can not say anything because I only turn on the device when I really need it on the battery life.
