I've tested T.38 sparingly.

In theory, yes.

However, many T.38 implementations are quite buggy.

Furthermore, T.38 over SIP+UDP doesn't entirely resolve the "jitter" 
problem with packet loss since UDP is still being used.  (T.38 allows 
for up to 4 retransmissions of every packet to compensate for UDP packet 
loss.  However, that doesn't guarantee that all 4 packets still won't 
get dropped.)

For now, if you're looking for *robust* faxing then I would suggest 
sticking to the PSTN.  If you don't mind a few problems and don't mind 
putting forward some effort in searching out and comparing T.38 
implementations, then you may want to try T.38.

Thanks,

Lee.
