Who called from 6366142902

just got the same call, the guy said hello twice before I hung up.  up in the twin cities here.

Just received a call from this number. Only answered because we do business with companies from all over.... heard a man's voice "hello", then nothing.  I thought I had a bad connection so I called back and the recording stated that it was not a good number.  
This only worries me because I know people can do strange things with these days and I hope it doesn't affect my cell phone.

Got a call from this number and the guy said hello and hung up.  Bloody annoying.

Got a call to my business number from a man, say "hello" and then hung up. Odd, but seems consistent with other posters here.
