Why Won’t “We” acknowledge change
Last week, I heard the senate passed a new bill that made it illegal to spoof caller-id. I wish I could remember the link that I read it, but I am sure you can find it. How absurd. Just like my blog about the guy who got caught stealing wi-fi, how can you get caught spoofing caller-ID. Technically this is what we have to deal with. Here is a sip packet, in it you will see the where the number is that displays the caller-id.
<ommited> technical difficulties
To spoof all you need to edit is the Call-id field. As simple as that. The only way to get caught is if someone is mirroring your traffic. That simple. The carrier only keeps cdr’s of traffic so that is only the source, destination, and call duration. They are not worried about what the call-id says. In order to block call-id all they have to do is edit the sip packet to exclude the call-id. It isn’t recorded. Make laws on something you know about, not VOIP.
New Zealand went totally VOIP. Their service offering is VOIP over dsl, which is the same offering Verizon has, but unlike Verizon they have entirely change the way the process Class 5 calls.
