You moron. Do you really think that an individual is calling hundreds of people and harassing them? It's a robodialer and if anything they are ghosting her phone #. Hell, I've seen my OWN phone number come up as the ID of these robodialers. Stop putting individual's name and address on the internet and calling them criminals.
I callled this number back and the messaging service is not set up for voice. This maybe someone has their phone set up to get into your computer. Do report.
