This, of course, will effectively kill the odoriferous putrescence that is robo-calls.
By December, all Robocalls must have a key or voice activated opt-out, and by the following September, robo-calls are prohibited, unless the marketer has “the prior express written agreement of the recipient to receive such calls.”
Prior business relationships have been eliminated as an exception, though medical calls related to HIPAA, and calls by non-profits to members have an exception, though the latter requires automated opt-out.
Note that political campaigns can still inundate you with robo-calls though.
