I have successfully used the Grandstream ATA286 and Linksys PAP2NA. I would
recommend the Grandstream over the Linksys as there is less configuration to
do and it is IMHO more reliable for faxes. I have been able to get analog
data modem connect at 48k on the grandstream whilst cannot get modem to work
at all on Linksys.

This will work provided that you can create a near-lossless
communication path between the ATA and the PSTN gateway (which is the
Asterisk box, I assume).
One way of creating that, I would expect, would be to add another
ethernet card to your Asterisk server and then run a crossover cable
between that interface and the ethernet interface of the ATA.
You'll also need to configure the ATA to not do lots of things typically
done by ATAs, like echo cancellation.
That's a good idea. I hadn't thought of using a crossover cable and a
dedicated card like that. (Though, that said, I suspect that the
datapath through our regular network switches is probably close enough
to lossless for this purpose as well.)
Any recommendations as to which ATAs are suitable for this purpose? I
don't remember seeing a way to disable echo cancellation on either the
Grandstream or the Sipura ones that I have here.
