So they are the same thing then. Thanks for clarifying.

true.... thats why I imagine there will varying interconnect charges
between ISPs based on the qos of a given channel.... a channel being
one voice conversation and another channel being a video conversation
etc

end user charges in the current world are fixed with a set usage cap
included and extra data charged per GB.... wonder if this charging
model will continue to hold in the brave new world.....

actually i would interpret what Nick said as IP Telephony **uses** VoIP
technology but adding more telephony like functionality such as the
list Nick mentioned...in any case, remains to be seen whether the term
gains ground... would IP Telephony include Video over IP?

Yes, that's exactly what I meant and yes it does include video. When I
was product managing a Softswitch we had all sorts of fun and games
trying to explain the difference between bog-standard VoIP and what we
were actually making, so IP Telephony became a useful handle. Signs
that the expression is gaining ground is that the likes of Avaya
(www.avaya.com) and Nortel (www.nortel.com) use the expression.

You have an interesting definition of "telephony".

Interconnect fees between ISPs? Oh, good, we can go backwards 20 years.

And exactly how do you think it works now?

I know exactly how it works now. But we don't pay every ISP we peer with
for the privilege. We pay our transit providers and we pay IXs to allow
us to connect to them.

My reading of the post I replied to suggested that the poster wanted all
ISPs to pay/charge to peer whether it is direct/private peering or
peering at IXs, and that this would give them some kind of QoS on the
network of the ISP they pay.
