No.
Something like defamation.
While publishing truth is a defense against a defamation lawsuit, it doesn't prevent the lawsuit from being delivered to your door.
Once that happens, how would you like to spend many thousands of dollars on a lawyer just because you were so small minded as to feel compelled to go tit for tat with the loser who sent you the voice mail.
I'm sure that there is more to the story about how this voice mail came about but my advice to you is ignore it, block the persons number, take the high road and have nothing more to do with that person.
Nothing good will come of escalating.
