Oh really? Spammers, scammers, and other scofflaws? Can’t think of anyone else who would want to do this.

Enjoy while it lasts. I don’t know how things are going in the UK but in the US there is a lot of active work in preventing spoofed calls from crossing the network.

I would say unauthenticated. Most carriers will allow you send whatever you want as long as you format it correctly. But they now keep records and if they get complaints they will drop your account.

Everyone knows that they need to be allowed to send calls back out with the original CID at times.

Been doing this for more than a decade and this is the first time I can recall seeing this. I have seen (and coded) for the case where CID needed to be chosen randomly from a list of fixed numbers, but I can’t think of a non-malicious use case where every single trunk call carries a truly random CID.
