Rule of thumb for me is if someone calls and lets it ring just once or a few times and then hangs up before I can answer, I dont call back as it may be scam or waste of time, besides if someone wants to reach you, its their progative to call you.
As for the other suggestion with the telephone preference scheme, not sure if that will instantly to resolve the problem. Check with your mobile operator to see what options you have to resolve the problem.
