If you started an auto dial program to dial phone numbers, then you can certainly stop it. What right do you have to tell us that if we don't like getting calls from you, we should change our phone numbers!!?? Thousands of people are upset that they are constantly getting calls from 417-447-4530, and then it hangs up when the phone is answered. What you are doing is known as harassment. You would be wise to correct this situation before someone gets upset enough to go after you legally.
