Unfortunately Phone has a 3-4 sec delayed answer. We can test the line, it is clearly on the phone. When do I register for example with the last name, the caller does not understand it. One can only after 3-4 sec. start talking. In addition, display very poorly visible, light blue on blue. You have to work very hard to find the numbers in the list. On otherwise a very nice phone, not to gebrauchen.Akku also does not last as long as cordless phones. After 4 days, must be loaded. After 3 weeks returned. Too Bad ...
