> identify on the caller ID as having the same area code as my normal phone number and my Google Voice number.
Most of my spam calls copy my area code and the first 3 digits of my phone number. In fact, I installed an android app called Calls Blacklist solely to make any call that began with the same 6 digits as me to not even ring - and now I get about 1 spam call per month.
Ooh, I need to look into that. I acquired my mobile number about 15 years ago in a town 20 minutes away where I know practically no one. I get plenty of calls that have the first 6 digits pattern and it is virtually certain that those calls will not be from someone I know. It would be great to have them never even ring.

YMMV.
