Using the Fritzbox with a cordless phone (PSTN) connected to either FON 1 or FOn 2 connection and cannot get Caller ID showing up.
Phones screen shows as WITHHELD, Fritzbox call list shows as UNKNOWN.
This is with caller ID available from BT and showing on the phone when connected direct to the BT phone socket a.
Also in Fritzbox telephony devices this is set:
Calling line identification presentation (CLIP) (set on)
Simple mode ( set)
This is the same if I register a dect phone to the Fritz base station , NO caller ID
Working fine on Fibre, but trouble getting the PSTN phone and Dects connected to the Fritzbox to give out caller ID
