If they get past my spam blocker then I usually let them start talking and then put the phone on mute and leave it on my desk.  It's funny how long they will talk before stopping to realize no-one is listening.  Waste my time; I have no problem wasting yours.

Thank you for sharing.  I get so many unidentified calls.  I also received a call from the number as well . . . however did not answer it.  It is now blocked!

Thanks for the info. I was about to answer the call.

Caller ID says ACCD . I got no response . Normally I don't answer calls I don't recognize , but I was expecting a call and this was an ID I had not seen before .

Solar System Selling ... They do NOT use the Government Do Not Call List and seem to get away with calling every number they can find.
