Have the phone bought as an alternative to our GIGASET because the handset for the 4000-he was not going to get series alone. So that part is now next to my computer. You can not expect much, the ringtone should be provided only to half volume. Everything else is annoying and impossible to describe. Unfortunately, the volume of the earpiece is not exactly high, so you have to press the handset heavily to the ear, or the area is fairly quiet so you understand what. As a substitute for people who call the little device is just to recommend. PS: When you replace the handset should be "neat" to hang up, because otherwise the other phones (parallel operation) are not working.
