Have you checked the installed version of firmware against the latest

Oh! I didn't guess to check. The firmware was not fresh, but upgrading
doesn't help.
Looking at your SIP information when your ITSP initiated a T.38
session it did not indicate a maxmimum bitrate, it would appear your
spa112 attempted to negotiate a connection at 2400bps.
Whether there is a way to force my provider to indicate maximum bitrate?
Do you have a sip debug session when you sent a fax from your Asterisk
box to the PSTN, it would be interesting to see if it sends it as a
t.38 or reverts to G711 audio.
I have collect a set of debugs (with fresh SPA112 firmware) and actual
config files:
== spa112 — cmd ReceiveFax
https://gist.github.com/anonymous/5701032
== cmd SendFax — PSTN
https://gist.github.com/anonymous/5701150
== spa112 — PSTN
https://gist.github.com/anonymous/5701207
== sip.conf
https://gist.github.com/anonymous/5701231
== udptl.conf
