I have a Siemens Gigaset A540 DECT phone connected to a Experia Box v9. Whenever someone calls, the phone does not show the caller's number. Unfortunately, the phone does also not show a "missed call" message when there was no number. However the numbers are shown in the Experiabox's logfile.
It looks like this is because KPN uses DTMF for CLIP. Is it possible to switch this over to the standard FSK?
