Great phone - to start with; but after 9 months the ringer would not work for incoming calls. Tried all the resets but epic fail. Had a GIGASET before this one so it looks as though I will go back to that make.

BT caller display

  (Rating Hidden)

Because of the font size used to display the number of an incoming call only the last 7 digits are displayed. This makes caller display virtually useless.
