Re: Caller ID Spoofing

>From what I've heard, the information is sent between the first and second
rings on your side. I'm not sure if it's possible for the caller to
transmit any information at that time (therefore overriding the
information sent by the phone company), but I think it's doubtful. So the
only way for the information to be wrong is if the phone company sends
the wrong information. I think the only way for someone to spoof it is to
make the phone call on someone else's line.
