Many Internet reports like the following one:
"Received call from this number, tried to call back message says not inservice. Must be a junk caller."
Spoofing a number is certainly a good clue... and accent can be a legitimate clue as well, because numbers of these originate out of the US.

She went on to say I won some prize, at which point I interrupted her telling her and her company to never call me again.
She then became angry and yelled (yes, yelled), "Give me a reason!" I told her I'm not interested in discussing this and hung up.
The phone number was (210) 228-4024.
