I'm not sure if this issue has been previously addressed. One of the useful features for Fios Digital Voice is "Call Blocking", in order to deal with telemarketers. The problem with using FIOS's call blocking feature is that it can only be used with a full telephone # (10 digits). This method is obsolete. Telemarketers now have access to hundreds of phone #s. What is needed is a type of wildcarding where you can specify just the area code, or first 6 digits for call blocking. This would stop the telemarketers from getting through. I don't see why this would be so hard for Verizon to do. The idea of having to input 10 digits for each phone # for Call Blocking is past its time, and not keeping up with technology, which should not be the case for FIOS. .
