@shirleymac, some phone companies have call features you can add to your phone line for a price. There is a feature called Selective Call Acceptance that may help if you can get it. Selective Call Acceptance allows you to create a list of phone numbers from which you are willing to accept calls. Callers with phone numbers not on your list hear an announcement informing them that you are not receiving calls at this time. Also, when this feature is activated, you will only receive calls from the numbers you have programmed. Emergency calls may not get through.
