Who called from 7189583166

No one is on the phone. When I call back the message says, "you have reached a non-working number, announcement 14 switch 8-5, whatever that means."

The guy who made the call asked for someone who actually works here, but then he said something sort of off color.  Something about how are you doing and are you keeping it up.  Then he hung up.

I get one or two of these calls a day.  The no. may change but it always says test code ny. If I pick it up, there is no one there, even if I wait. No message, no nothing. VERY ANNOYING and I wish they would stop. I block some of the numbers but then I get called from a new number.
