Who called from 2545802400

Called the number back and got the "Not a working number" message.

Silence

The only reference I found for this number was an Italian restaurant.

-Verona Italian Restaurant 254-580-2400 - 305 Coke Ave, Suite 100 ...-

As mentioned, dialing back gives a disconnected number message.

Got a call from a lady at this number. She asked to speak to my boss (by first name) and I told her that he was gone for the weekend because he's a slacker and she hung up on me.

Also got a call where she asked for my boss, I told her he was not in, and she promptly hung up on me.  Like I would've let her talk to him even if he was here.  I hate telemarketers, esp the rude ones!
