Phone broadcasting is a technology that allows you to concurrently deliver hundreds, even countless numbers, of messages people could hear over the phone. It is also referred to as voice broadcast, blast, phone blast, and in the political world as robo calls.

This is a highly regulated area and commercial telemarketers tend to be facing elevated federal and state rules which make it increasingly more hard to send out pre-recorded messages. More than half of the telephone numbers in the United States have become on the Do Not Call registry and telemarketers usually are not permitted to give them a call. Furthermore, brand new regulations will demand telemarketers to get written authorization coming from those individuals they would like to call.
