try answering it... i have called my mother 4 times this morning and 3 out of the 4 times this number is showing on her caller id and it is me calling... sprint has no idea why.
Called me from this number on my work cell phone and said he was from Microsoft and that the computer I was using had a virus and I needed to download a program to fix it that it was a new virus. I shut him down immediately and hung up. He tried calling back, but I refused to answer.
Got a call from this number to my cell phone number, I didn't pick up and no message was left. The call was forwarded through a service that notifies me of calls, and the call notification was reported as "MD STATE GOV". According to online sources this is supposed to be a University of Maryland number (out of Adelphi, MD/UM Foundation Inc) but I have no idea if that's true. From what other people on this list are reporting, it might have been "hacked".
