Who called from 9707442335

This number has called our office multiple times, but only rings once. When the number is called back, there is nothing there - no dial tone, no message that the mail box is full, no busy signal, nothing but dead air. I assume it's a number looking for live telephone numbers.

Still looking for suckers.

Scam-bag hung up when I answered the phone.  Blocking # now, let the bottom feeders listed to a dial tone.
