[VoiceOps] Future of the Traditional PSTN vs VOIP and VoLTE

These are the crux of the issue. If there were a cooperative group willing
to peer to circumvent the PSTN, and if the group were large enough, then it
could offer *some* competitive pressure to get the ILEC's to change. In
fairness, Verizon and AT&T have been petitioning and hit some roadblocks by
the FCC to retire their legacy networks. Some of these concerns are legit,
some are not.  Now, I'm not naive enough to believe these petitions are for
the good of the consumer or for anyone other than Verizon and AT&T. But
technologically, it's a step in the right direction.

But for the signaling issue mentioned above, there could potentially be a
new DNS record type created which defines accepted signaling.

Trust is a whole different problem. Without a central authority, it could
be chaotic and really difficult to manage. But I think the BGP analogy is a
good one. If there could be a method of passing info and then either
allowing or blocking it would be ideal, but it is a really big shift in
VoIP security, as was pointed out.

That said, anyone interested in setting up a lab environment to hash this
