I think it is a international call (from india)... rather than getting the actual number sometimes, ATT or some other exchange sends the local exchange's number...
I have been getting two or three calls per day from this number. When I pickup, no answer and when I call back, the call is not going. Most likely prankster calling just for the sake of irritating people with spoofed ID.
