2) Packet loss, etc...makes faxing over the internet unreliable
I'm not sold on this theory yet. I don't think that it's so much a
matter of packet loss (this shouldn't occur regularly), but rather of
latency. Transmitting packets over a network, and in particular the
internet, can result in latency delays that could, in theory, pose a
problem for FoIP, but I've heard of so many people successfully doing
FoIP with equipment other than Asterisk (i.e. using Cisco VoIP
equipment), that I tend to believe that the reliability factor is more
a consequence of SIP or the equipment used (Asterisk and, in my case, a
Sipura SP-2000).
Actually, I thought it was more related to jitter than latency. Consider
that faxing over international PSTN worked reliably back in the bad old
days when international calls were sent over satellite (Well, Australia
<-> US anyway).
Just my 0.02c...

Latency isn't really an issue. Packet loss can be. Jitter can be. So can
other timing issues. Look here http://www.opencall.org/faq/x29.html
