Oh, that's interesting. I didn't know such stuff went on.

We haven't had any trouble with VoIP, but maybe we're lucky to not
have much local contention for bandwidth. Still, it shouldn't take
much bandwidth to support two-way audio: if their QoS algorithms are
at all reasonable, latency should remain low. I wonder if they've got
their IP routing sensibly organized like that or not. I'll have to try
making calls while doing big uploads or something.

Not, not at all, I'm afraid.

It's an interesting idea. I don't know how well faxing survives the
audio compression that they use, though I find it plausible that it
would work well enough.

Largely it works well enough for me to move image files around on the
Internet, and to give my employer a few cents for occasional use of
the fax machine at work. (-:
