Since you have a landline, just unplug it from the wall for a few days unless you have to make a call...nothing tells someone to go away when they stay on the landline and subject themselves to the 22 rings to nowhere...(generally when an AT&T landline is unplugged and someone calls into it the return rings 22 times before going silent).
