copper has nothing to do with it. You're talking about conventional PSTN
(circuit
switched) technologies.
Even more succinctly, it is the difference between streaming and packetized
data. Circuit switched isn't even a necessary qualifier. Dedicated bandwidth
with minimal buffering is

Hi,
A lot of people talk about grooming to make VoIP work smoothly, not just
for FAX. However, most people can only achieve grooming in one
direction. Their ISP will not cooperate, and groom what is sent to the
subscriber. Unless you just keep your DSL link very lightly loaded, by
doing no

It's exactly the kind of mail with NO interest at all.
We all know that fax is an old way, for sure, but not all the users

If T38 exist, it's to transmit faxes over IP because some users needs

Thanks Brendan for the explanation. There is one other idea that struck me,

It should be wise to also ask your ITSP as T.38 interop is far from easy ...

People can't figure out e-mail as it is, they aren't going to figure out how
to fax via e-mail..
I can understand people saying that. Myself, I'd take E-Mail any day. I've
been messing with FAX at various facilities for years, and have found it
unreliable, as have most people I talk to.
I think Brendan is asking about endpoints (how to connect fax machines to
pure VoIP).
Short answer:
- you could connect standalone T.38-enabled analog gateways to 1.4,
- with 1.6, you can also use an analog board inside a server and connect fax
machines to this board.
