Hello, <SNIP> How can I protect aginst a faked called ID ?
I understand it's practically imposible to do this without the help of the teleco provider.
practially to protecet without the teleco prov. or practially impossible to fake the caller id (didn't tried it but this seems to be possible)
I was thinking of the latter - people here will be able to give better info I expect, but the way I understand it the CLI originates at the exchange the source line is connected to and is used for routing the return leg of the call handshake: so the teleco would need to do the faking, and if it was faked the teleco would need to know so the correct routing can be done.
