Wanted to know who owns this number.

called me 12 times between 4/22 and 6/3, never left a message.

1307 hrs.  Left no message.

They've called every weekday for a couple weeks now and never leave a message.  This morning, I answered it and nobody said anything. After a moment they hung up.  I called them back and there was no answer.

Some dork called to offer my company 'Safety Training'. I asked if they abide by the DNC list, as my number is on it. Of course gave me a long story. Had time so I kept them tied up on the phone for 10 minutes, figured give someone other future caller 10 minutes of silence before they called to bug them.
