The problem with both those suggestions is that it's trivial to fake the "from" phone number, as evidenced by the number of spam calls that share my area code and exchange numbers.
(Last time I setup asterisk with a T1, this was also trivial, but that was like a decade and a half back. I couldn't tell you how to fake your number today.. it's just clear that it's easy for the scammers to do.)
The first problem we need to solve is to make it hard to fake your number.
- geocar 8y agoIt's easy to fake the "caller-ID" field, but this doesn't fake the ANI: If it did, you could call 1-900 numbers and bill the White House. You're right about there being a lot of little legacy problems though; The issue I see is that the carriers aren't on the hook for it: They've made it so cheap to call someone these scammers simply need to find people whose time is worth less than mine.
- grecy 8y agoIt's going nothing to do with the "from" number, get in at the carrier level. Who are they buying their connectivity from? Implement it there.
