This "Outreach Assoc" group called me from 412-773-8566, 8570, and now 8574. Each time I have blocked them and I will continue to block them, no matter what number they use!
They've called me four times in the last five days. They are fundraisers who call on behalf of charities, political parties, candidates, etc., that you might have donated to at one time. Just tell them to take you off of their calling list. When you answer a person will come on in about five seconds, because the calls are generated by an automatic caller, which indicates to the caller that you have answered. Political parties are exempt from the No Call List by law, so that's probably why you still get them.
