As usual, it's not that complicated, and it's not that simple. The simple solution would be for the network providers to validate the caller ID numbers for its subscribers, but that requires changes to punish the ones that don't do it. I've worked with telephony for 15 years and I know the big providers do this for most common telecom protocols, but VoIP providers tend to be more lax. But that's where they shouldn't,…

Yeah, but they can at least do the following things:

- Don't connect calls coming from numbers they own that they have not assigned

- Don't connect calls from a number to itself (my wife recently received a phone call from "herself". Then she received 20 more phone calls from irate people sure that she spammed them)

- Don't connect calls where the calling number is coming from an invalid area code or LATA

- Don't connect calls where the calling number is a string of only digits. There are no people or businesses with this type of name, most likely.

This would solve between 10-50% of the spam calls I get, I'm pretty sure.

Sign up for any random SMS API service. You'll note that you can send SMS using anything you like as the 'from' field. There's no checks or restrictions. Same goes for voice calls in most cases.

Which ones actually support this? From what I've tested, T-Mobile and Verizon will both fail to deliver SMSes that aren't originated by the carrier listed in the SMS routing for a phone # (which is wholly separate from the PSTN routing of a number, and can be a source of problems when changing cell carriers).

I'm using the noname brand resellers, not the carriers themselves. I guess that's why.

I've tried a dozen thus far to no avail :c

I can hijack SMS routing entirely for inbound/outbound, but short of doing that I can't forge the from field and get the message delivered.

Except when we provide you 4g and 5g coverage, ensure societies have working critical infrastructure to communicate peer to peer and in addition gives you a nice fiber pipe to your house and handle all the carrier dealings of broadband interconnectivity. Oh yeah and tie this all together with advanced roaming deals and functionality which connects countries around the world. It's also us who pioneer and really implem…

I for one was not speaking for US Telecoms whatsoever.

Fair enough! That's why I limited my comment to US telecoms -- they're the only ones I have any experience with.
