I really don't know why DUNDi has even been considered as something
that can be used on a global scale. It isn't something that is
efficient nor is it something that I would trust to scale beyond the
enterprise level.

Hi Simon,
Researching DUNDi opportunities is on our product roadmap for Q4 of
this
year. We think your idea makes economic sense for CLECs
(Competitive Local
Exchange Carriers) in the US. We would like to collaborate with
you on your
effort. We will be able to contribute some hands-on effort
starting in late
September.
Until, then we look forward to discussion about what is needed for
DUNDi to
be useful for the carrier market.

Subject: [Dundi] DUNDI for inter carrier exchange
Hi folks,
I'm new to the list today so please forgive me if this is the
wrong place to post this.
I've been looking at DUNDI for a while and have implemented
it internally. It is very impressive so thanks and praise to
all those involved.
The next stage for us is to implement it externally but
whilst thinking about that something comes to mind. Is there
scope within the specification to advertise rates, or has it
already been discussed?
Before you set about me, let me explain:
- Yes, there is the obvious 'live LCR' type scenario where
multiple termination providers could advertise their rates
and any that are interconnected could be sent the call. That
has a place but isn't the bigger application.
- Of much more interest is the inter-exchange of traffic
between carriers. I'm in the UK so the following may not be
appropriate elsewhere but every call in or out of a carriers
network results in a payment to/from the peer. The sum of
those makes up the outgoing call cost but, more relevantly,
represents an income on the incoming call.
Currently, a carrier is better off receiving the call through
PSTN than advertising a VoIP route through DUNDI but if they
could publish a rate then their peers could choose the least
cost route. Implicitly this would lead to lower costs for
both parties even if the direct cost/revenues remained
unchanged - carrier a could route to carrier c over VoIP,
avoiding carrier b. Carrier b receives the call directly and
gets the same income as he would have done from carrier c
without the costs of the traditional interconnect.
The second option is possible now between any two peers but I
do think if it was built into a protocol like DUNDI it could
give it significant traction and make the benefits of peering
two-way. Taking my company as an example, it only makes sense
to advertise routes to numbers on which we receive no ingress
income. The vast majority, even where they terminate to VoIP,
would not make sense as we'd lose the income.
Granted, that income subsidises an expensive interconnect and
the call would be coming over a much lower cost one, but
there remains a real cost. Further, we offer numbers where
the income directly funds another service such as overseas
diverts which it would be impossible to advertise. If we
could advertise them with a rate for interconnected peers,
other participants could send traffic through on
inter-carrier terms and we'd have the same income on a lower
cost base.
It strikes me that this would really give the system traction
and cause the kind of disruption to the traditional
marketplace that is long overdue and ultimately benefiting
the consumer.
Looking forward to your comments.
Kind regards,
Simon
PS - We'd be happy to make UK toll-free available as well as
publish our own voip terminating numbers if a local peer
could contact me off-list.
