I have gained the BT6500 quad set. Unfortunately one of the phones has died so I purchased a replacement. It won't let me register the new phone. I obviously can't de-register the dead phone so is there a way of clearing all the registered phones from the answering machine base and starting again? I have tried to re-set the base and pin but it keeps stating that the function is not available at the moment.
Many thanks, I tried that, but it still won't accept the new phone as the old one is still registered but can be de-registered as it won't switch on. I also still cant re-set anything.
