Why can't my provider, Telus, block spoofed caller Id. For email we have SPF and Dmarc, I haven't had an email with spoofed from address hit my inbox in years.

Why can't my provider, Telus, block spoofed caller Id. For email we have SPF and Dmarc, I haven't had an email with spoofed from address hit my inbox in years. Similar to the internet the phone system is connected through peering, sources of spam should be dropped like bitcanal.

Currently it works like old school (physical, postal) mail -- the sender writes something on the envelope that says who they are. If every robocall received gets you five cents off your phone bill, it'll be solved within a year.
