I let call go to vmail - it was a call on our house phone (I know, I know - probably one of last people on planet that still have one). No message was left. Unfortunately, our phone company only lets us block up to 30 numbers. We get so many unwanted calls a day now on our cells and on our house, that it is pointless to block them. Just have to learn to ignore and let them go to voicemail. ALSO SOME ADVICE - there is a scam going around when you answer your phone and they ask if you can hear them - and you say "YES" they record your voice and do something very nefarious with it - I believe the scam is in more detail on the FCC website. Please, if you do answer the phone, try to have a very limited conversation with them, or ignore the call and don't answer like we do, and just block the number. Of course report it if you do find out who the annoying callers are so the rest of us know it was not an important phone call that was missed. Apparently the "do not call list" does not matter anymore and more and more scam artists are "masking" their phone numbers and annoying more of us helpless Americans.
