Strong security and authentication is important in a system where you have
in-band signalling, and everything is visible to (and reproducible by) the
end user if not for other users protection, but for the protection of the
network itself.

If the fault of the original phone system was that is was a closed system,
as is often stated by those working on IP telephony, the fault of the next
generation phone system, cheap or not, is going to be security and
reliablility if we're not careful.

Agreed; the dangers inherent with in-band signaling are readily apparent;
remember the Cap'n Crunch bandit of the '60's phone phreaks.  /m.
