No response when I picked up, caller disconnected

Hangup.

"How do we make this stop?" Just check the manual for your phone service. For my provider, I can key in a number or simply tell the system to pick out my last incoming number, and then I have it forward all future calls from that number to any other number I desire. One option would be to send all nuisance calls to 206-496-0950 (!) or another of my favorites. But I think the best bet is to forward it to 888-382-1222. That's the dialup number for the Federal Do Not Call Registry.

Sorry ... I have been reporting these calls for years, and it simply doesn't work.  The FDNCR is useless.

Im tires of them calling and hanging up, its really begining to get annoying especially when i am on the DO NOT CALL LIST!!!!!

I would be very skeptical...see my note below.

Called and hung up!  2nd time this week!
