Probably so. I see some of the spam calls coming from phone numbers that are
seemingly right next door, as in, same area code and same three prefix digits
as my own land line. If that sort of thing were not permitted, filters would
work better. By the way, the technique of checking back to see if the source
address is valid is a technique used in Internet security. One name for it is
"reverse path forwarding." Mail servers, routers, security gateways, etc., can
use such techniques, and block any packets where the check fails.
Your suggestion of a private filter already exists. I have Xfinity home
phone service, and Comcast offers a service called Nomorobo
[www.nomorobo.com] that automatically screens all incoming calls and
compares them to a continuously updated list of robocall numbers. 99% of
the time my home phone will ring once, then stop.
That's pretty cool. Although some unsolicited calls are manual and some even
"legitimate," so a true white list would be even more drastic. Of course, you'd
also miss some phone calls that might have been appreciated!
