Yes, you can.  For $35 - $50 you can purchase a call blocker that can block up to 1500 numbers including entire area codes.  Most can be set to suppress the first ring so you never even know they called unless you check the list of blocked calls. Some can even be programmed to only allow numbers you enter to ring with directions on how to reach you if their number is not on the list.

Caller ID says Verizon ... But when answered says shipping dept and medical supplies package is ready to be shipped ..hung up

Are all of the supplies approved by the FDA? Maybe such a question will have them shaking.

Yet another flim-flam call from the flim-flam man.  Bring back any memories?  I received the call at 3:22 pm PST.  My CID said VERIZON, with the coma.  I stupidly answered to hear that my medical alert product was ready for shipping or words to that effect and hung up before listening to whatever came next.  Newly armed with my consumer rights I was going to tell Verizon all about how they should not be calling.  I will be reporting to all appropriate places.

That was suppose to be "comma' instead of "coma".  sometimes the auto-correct on my new iPad gets me but this time it was me.
