On anything other than a LAN, you will need to use t.38 to add fault tolerance to your UDP traffic. The latest version of Asterisk (1.6) has the most t.38 support of any version -- allowing for more than just pass-through. Asterisk 1.4 will allow for t.38 pass-through with the correct entries in sip.conf but you will need a your provider to support t.38 (arrival telecom) and you will need a sip device that also supports t.38 (Linksys spa2102).
This sounds like a good topic for a UTAUG meeting -- anybody interested in having one of those again?
yeah... i wondered where the group had gone ;-) Can anyone recommend a good provider that supports t.38 and is not a freaking fortune? I am currently with binfone for sip and have been REALLY happy with them. They just dont support the t.38
Once I get that I am sure I will have questions on how to actually set it all up.

The only solution that I trust is a TDM solution for fax. In my
installations I've always had a separate analog line for fax (which
doesn't even touch my asterisk server).

I let fax and modem run through asterisk at my former employer, but that was all zaptel, no packets. PRIs coming in and cheap ebay channel bank (carrier access) to analog lines. Zero problems.

I haven't used their t.38 service, but Eliott said they have it, and
ArrivalTel is a good price. I have run analog fax through their
service (without t.38) with good success (lower failure rate than I've
gotten on other services, don't know what percentage, but I don't
remember a failure off the top of my head - YMMV). I use IAXmodem to
receive faxes, but a physical fax machine connected to a linksys PAP2
to send them (I turned off echo cancellation in the PAP2 for best
results).
