Got a call from this number at 3:26 am CST on my cell, which is both work and personal. Did not answer it of course, but that makes me suspect it is overseas. 971 is the country code for United Arab Emirates and 91 from another message here is country code of India.
Was called at my office to verify my name and title. I repeatedly asked what I could do for him. He abruptly hung up, and will not answer a return call.
Also received a call from this number at 10am EDT. Left no message when I did not answer. It came through the caller ID with a 9 prefix (9-714-360-2824).
