I just got a call from this number on my cellphone too (after a missed one last week).. a lady asked for me by my first name... but the line was really bad and she couldnt hear me.. I am in New Zealand... must be a scam.. but what on earth are they trying to achieve?
Shows as U.S. number (+1) on my cellphone. They called every evening for a 2 week period in December 2012. I never picked up once, and they never left a voicemail. Haven't had a call since.
