I just received a call from this obviously hijacked #. A Google search shows that it belongs to a Women's Health Club in Boston. Since I live in California, I don't believe it is a call for potential membership.

12:22 PM PST/This unknown caller's unanswered call sent to v/m left  no message.  I never answer unrecognized numbers and if they can't leave a message; it's not a legit call anyway.

Got the call from this number; let it go to my answering machine and there was only background noise with mumbled voices.  Going to block this number right now.

"Your call cannot be completed as dialed, please check the number, blah blah blah"

Block this number, it's a scammer...
