Who called from 3148148865

Received a phone call from this number yesterday. My caller ID identified this number.  Left no message after recording came on.

Rec'd call on 10/2/13 at 12:01 pm
only # and "out of area" displayed on caller ID
If/when I want details about call in order to decide which to report, I answer, only saying 'hello' w/a dead-pan, robotic-sounding voice ... then wait to see if call continues ... however, this caller chose to hang up before I even got the whole word out.  Makes me suspicious it's a 'pharming' call ... one that seeks out numbers that actually connect.

same thing as above. No one spoke to me when I answered.
