When telcos moved the control signals out of the comm channel they also made those signals physically inaccessible. Nothing could be done at the telephone end that would inject arbitrary control signals. (Am I correct?)

Now, if we look at the current internet from that point of view, then everything that enters and exits the computer is inband. We can alter every bit and construct custom packets and send them out.

So…

- Is everything we do to encrypt/encapsulate/obfuscate not inband signalling?

- Can true encryption and security only be achieved by having the intermediary (telco) doing it for us?

Just picking your brain, btw.
