Can somebody who works in the industry explain why it's so difficult for telcos to trace and block a high volume of dodgy calls with spoofed caller id that are likely originating from overseas?
- hot_gril 3y agoI'm guessing the part about it originating overseas makes things difficult. Phone has similar auth weakness as email, another kind of federated communication. In this day and age, I can still get a fake email "from myself" in Gmail, and it can't even be sure that it's fake.

- supertrope 3y agoThe Public Switched Telephone Network is effectively a series of proxies. Some of these are in foreign countries. Each phone companies earns revenue in proportion to the volume of calls flowing through (termination fees). Upgrading their legacy PSTN switches to SIP softswitches that support SHAKEN/STIR costs money. No one wants to invest in a legacy market (voice calls). So they have an incentive to delay deploying countermeasures.
