I hate to be such an old fuddy duddy, but I think this might run slightly afoul of Rule Arkansas Rule of Professional Conduct 7.3. I understand there is a constitutional question whether the rules against direct solicitation can properly be applied to robocalls, but I'll leave that defense up to the guilty culprit responsible for this unseemly method of marketing.
Unfortunately, I don't know if there's any way to catch the lawyer responsible (if indeed there is one). Research on the Internet shows that the number is used by a generic telemarketer who does more than just sell legal services.
There are plenty of legitimate avenues for advertising. Telemarketing is not one of them. If you are solicited by a telemarketer please beware!
* something like: I was killed in an accident with a drunken Penthouse Magazine delivery truck driver who got out of his truck in nothing but a scraggly beard and high heels, laughed at my corpse, poured his beer on it, and then got in a fistfight with the investigating officer.
