This is a nice wish list, but without legislation that requires it's use and
with the percentage traffic that goes between two VOIP providers being so
miniscule (anyone have those numbers?) this is a LOT of work for very little
return. Most providers who switch calls in the 20 CPS+ range are also
unwilling to add any additional overhead to their call processing and don't
fool yourself into think that VOIP peering is settlement free. You will save
a little - but at what price labour-wise?
You could achieve what you're after with a private ENUM tree that providers
publish their subscriber numbers to, but this also means providers need to
work ENUM into switch deployments that probably have existing IN
functionality. They'd probably prefer a flat-file transfer which they then
process internally and add to their IN platforms database for route lookups
- much like how number portability systems work in Australia. How do you
handle disputes that arise when two providers claim "ownership" of a single
On the service assurance front - who do you yell at when it breaks? What are
the consequences of it failing to work properly?

OK lets cut to the guts of the problem. How do we get VoIP peering
sooner rather than later ? Tomorrow, yet another year will have
passed. Progress starts today.
Assumption 1 - The big T(s) make about 50% of revenue off the PSTN
equivalent to about $2.5B, so don't expect any co-operation.
Assumption 2 - it has to be neutral - the Govt should NOT be
involved. Of course they are welcome to peer, in fact its a surprise
that Govt depts don't have inter-Dept peering already, its a bit of a
no brainer for them. Maybe GSN was going to get there......
Assumption 3 - it has to be simple, so that VoIP providers and end
users can get involved. (besides I'm on holiday and my horizons are
sleep, food and beer)
Assumption 4 - It should be distributed and scaleable.. (are you
peering with your city, your region, your country or the World ?)
So we need something NOW, that can be migrated if required. But we
shouldn't be waiting on committees or politicians.
