Few companies over a certain size run their own call centers. It's no different from a software startup using AWS or Rackspace instead of building a server room in their rented office space. I think it is both acceptable and desirable for my phone to tell me Comcast is calling me (as they currently do), even though it's technically an outsourced call center that makes/takes calls for several different companies from the same building and same set of phone numbers. Requiring caller ID match the billing address for the phone number would be like requiring Hacker News be hosted on a cloudflare.com subdomain because the IP space we're talking to isn't actually owned by YC.

  You can set the CallerID name to whatever you want. We once had a customer that set their callerID name to "DEAD" to signal that the phone number was no longer in use. People thought they were issuing threads on their outbound calls.

  SPF records are reasonably simple to set up and something similar would solve this issue completely.

    To build SPF for the PSTN you'd first have to build DNS for the PSTN, then convince the manufacturers of carrier-grade switches to implement it, then convince telcos to buy new switches, then convince every single telco on Earth to throw out its last remaining equipment that doesn't enforce "SPF" for caller ID (or spammers would just use those companies).

      DNS for the PSTN exists, e164.arpa; mostly not public though. It would be a slog to get it implemented, but if spammers are limited to spoofing international numbers or from rural carriers, that's still a win because I can ignore calls from out of the area.

        More specifically (in case anyone wants to know more---I know it surprised me to learn that caller name information is sent via DNS) NAPTR records.
