I have logged a ticket but we haven't been able to figure out the problem yet. Support says it is a Verizon issue.

I have a caller who has been calling my phone with no problems until around the 11th or 12th of this month. Now his calls will not go through. I have "block all unknown calls" checked and have not changed this. The caller is with Verizon Wireless and he went to Verizon today and they have checked his phone and can't find any problems on their end. They are trying to say the problem is on my end. When I turn off the blocked call feature and the number calls my house it is showing up on one caller id as "out of area" and on the other caller id as "private number unknown number". I have not done anything different on my side and all of a sudden it stopped working. The caller can't even call in using the *82 before my number. I have blocked my cell phone and called and it wouldn't let it go through but when I did *82 and my number it went through. Can anyone explain what is going on?
