I don't know the technical details, but I know this is trivial to do if you have Asterix setup to manage your POTS line.

- viraptor 14y agoActually you cannot spoof a number on your own pots line. At least not a standard end-user line, because that one's connected directly to your telco and is bound to one specific id. But if you have a trunk with your own control channels (so basically you and telco assume trust between each other and that you provide correct information) you can publish any numbers you want. It's quite popular with the internet telephony providers to relax the rules a bit. Basically some allow you to check the "I promise not to break the law, believe the data I send" and will accept any caller id you want. Since there's no way for one telco to verify other telco's source numbers, everyone else has to believe your caller id too.
