[ale] OT: blocking phone numbers

[Phil Turmel]

Those aren't the callers' real numbers.  They are spoofing their caller 
ID to make it look like a neighbor.  (Easy to do with bulk Voip 
providers, unfortunately.)

If you block them, you really can block a neighbor.

Supposedly, there is a move to require crypto-signed authentication of 
caller ID at the provider level, but I gather providers are dragging 
their heels at the expense/liability. ):
