Who called from 3102323232

Received a call, nobody on the line and they hung up after about 15 seconds

Thank you so much!  Very grateful for you taking the time to post this information.

These idiots call everyday, they never leave a message and if you do answer, they hang up on you.  I'm guessing more Scam/Spam telemarketers.  

keep calling no answer

Another hangup call.  This means they are using a robodialer, and no one in their smelly, sweaty boiler room was available to pick up the call.  Robo dialers are illegal for telemarketers, but these creeps don't care.
