Who called from 8607542380

Got call from this guy 2 times in a row, called them 2 times, first one was "Call from '...' *BEEP*" second one was "Call from '...' *BEEEEEP*" Then it asked me to proceed message or send, I did nothing with playing with the voicemail, nor did I call this guy. Maybe its the stupid evil operator from prankdial.com or something. But please, find this guy. The ID on my phone said it was from Manchester, CA.

I received 3  times in a row from this number and got a  beep when I answered ... the I got a call from a Blocked number right after that and that left a voicemail that was just Beeps.
The number came up Middleton , CT on my phone

I had the same experience with the beeping calls to my office number. Recognizing that it was a fax machine trying to connect, I forwarded my office phone to our fax line, so the next time it attempted the call, it connected with a fax machine.  
The caller is Aetna Insurance--the number reads as Hartford (their HQ) but this one was actually from their Dallas office (I am in the DFW area).  I called the sender, informed him of the error (and suggested he correct the fax number they have for the intended recipient--a local nursing home), and shredded the fax (with its HIPAA-protected patient information.
If you get calls from this number, and can forward them to a fax machine, that will end the attempts to make THAT call.  It will also provide you with the voice number of the sender so you can request they correct their contacts list.

This is a company, you are sending a fax on our Sr Manager's phone line. He need to have this line open for phone call only. So please stop with the faxing of the fax.
