Price-performance ratio is very good at this phone in my view. I especially also my point of view is the "internal" calls resolved by the individual handsets. Two quick keystrokes and you are connected. The phones show kindly as which internal number you are logged in. Too bad that you can log on to the station only 4 mobile parts. The star deduction is available for a absolutely no-follow me point. When issuing the phones (do not remove the battery, but simply out) then "forget" the device date and time and they have to be readjusted every time. Why, no idea. Phonebook entries are between Advised copied, only individually.
