Who called from 2136404981

Called my cell phone in NY,   I ddnt answer.

rang twice and got disconnected before I answered. looks like they are fishing for real numbers.

My guess is the it's an automated system that is dialing thousands of numbers every minute verifying to see if your phone number is active. That's why only 2 rings. If it rings then that means your number is active. They would then sell this number as an active number. They probably already have your name and other details. Simply block it.

Great point, will do!

Three rings immediately placed one right after the other on 2/4/2016. No voice mail left, caller unknown. I blocked the number.
