Useful, but not more

The phone does his services, is to use but a bit cumbersome. It is particularly annoying that after each missed call, the LED in the speaker key flashes, even if the call is from a parallel apparatus is answered from long. How to switch off the flashing light, I have not yet figured out. So for weeks it flashes just to himself. In addition, the very light handset is very uncertain on the device. Since my desk is not always tidy, it often happens that I unnoticed slide the phone out of the shell and the line is busy.
