How would such a black box cause any upset to a prerecorded call possibly a black box type device?
I was thinking more in terms of real live telemarketers.
But I was actually thinking that telemarketing firms should be required to put in place a method for detecting when a person they’ve called pushes the number 1, automatically removing their name and number from their dial list and disconnecting the call.
No automated system in place, no permit to do business as a telemarketer.
