[VoiceOps] Does anyone implement RFC 3219?

[Jonathan Thurman]

I am not a carrier, nor do I intend to be a carrier.  My view point comes
from working in K-12 education where saving money is a high priority.  I
wish we could get out phone number assignment from ARIN and deal Voice like
we do IP.  Of course you could have issues when you open up and start
trusting others, but I would say that BGP works.  It is going to take baby
steps to change the way that the telephone industry provides services, and
those changes are probably going to be grass-root type projects.  David, you
are right that I probably live in a different world.  While it might be more
bleeding edge that you can afford, it's coming.  Otherwise we all might as
well turn our SIP/H.323 devices off now and go home.

So the reason I initially asked this question is that we are looking to peer
with other agencies.  I have looked a many of the different
ideas/projects/technologies out in the wild and I like TRIP.  ENUM doesn't
change anything.  Someone still holds all the keys, and you are constantly
querying for the answers.  DUNDi is closer, but still requires more time to
complete the call when you have to search every time how to route it.  TRIP
lets you hold the whole routing table, so you know how to get where right
away.
