Received call from same number on 9/24/12. I did not answer, no message was left. Only one call received, however, was followed by two more calls from a different number ((575) 546-1575 the first time), and from (+57 (5) 546-1575 the second time). Same thing, did not answer, no messages left for either call. There is a thread on this site for the (575) number, says the call originates from New Mexico.

Who ever called 9-10-12 at 9am I did not recognize the number so I did not answer. They left no message.

I received a call on 9/7/2012 it hung up and nobody on the line.  When you try to call back it gives an error message.
