Have the headset receive very fast and loaded 15 hours after unpacking according to the instructions first. After logged in without any major problems at the base and (Siemens Gigaset model) 'Internal switch' a catch in the settings under Special Conditions set. Incoming and received on the handset calls can be played back by pressing a button on the headset over selbiges (conference). After ending the call by pressing the headset button I still had on the handset to hang up, press. With outgoing discussions I'm still not sure about the processes. Voice quality is quite adequate and the transmission quality in my existing range of about 10m also. Not satisfactory, the geometry of the retaining bracket. At least in my copy of the radius of the hoop is too small, so that the headset sits exactly and much too loosely. I conduct the bracket so to his place, I think that he should sit, it pushes back against the immense ear. I'm going to warm up the bracket by means of hot air gun and a little wide. If, as described by other users, the breaking bow, I will from 0.8 - 0.9 mm spring steel wire turn a new (from the dental technology) and possibly cover them with heat shrink tubing.
