BT Premium phone won't disable the call block on it. I've been into BT Call Blocking and turned it from on to off. Then underneath is "Blocking mode" with Custom, Announce or International. Mine is on Custom.
When I try phoning my home number from my mobile, withholding my number I get, "Welcome to 1572. The person you've called has chosen not to receive anonymous calls. Please dial again without withholding your number."
Any help would be appreciated.
