I just try to not let it bother me. I get the calls on both my landline and my cell. I hang up on all recordings, and say "No thank you" as I hang up on all unwanted human callers. I never press any numbers on any in-coming calls (I heard years ago that your connection can easily be hijacked when you do this - no idea if this is true or not). If I am really annoyed then I phone someone. If I call a friend or family member which I haven't talked to recently; both of us enjoy our conversation and we both get the added benefit that neither of us will get any annoying calls while we are using our phones. Life is too short to fret about things we cannot change.
