The use case for caller id spoofing is when the callback number is different than the number you are calling from, most commonly to present a generic (possibly toll free) customer service number when an agent who might not even have a DID number makes an outbound call.
Large operations might also have trunks from multiple carriers for redundancy, so simple ingress filtering is not necessarily viable.
- wtallis 11y agoIngress filtering is totally viable. A telco should strip any caller ID information that is not coming from a trusted source. If a customer operating a call center wants to spoof caller ID they have to prove to their provider that they own the one number they're spoofing. Caller ID from shady telcos should be removed and customers given the option of not receiving such calls. None of those rules are at all difficult to implement.
