This seems crazy to me. Why are you recommending it?
Because its the industry standard last resort of anyone who doesn't
understand FAX and is using T.38.
Even HP recommends for their own fax machines it numerous times:

Yes, always a last-ditch effort, and if it actually succeeds in getting
a legible document through then it means that either 1) the ECM protocol
on either the sender or the receiver is gravely flawed, or 2) something
that requires ECM (like V.34-Fax/SuperG3) ended up being disabled along
with ECM and that the problem really had to do with that something and
not with ECM. I've never seen a fax document that couldn't make it
through with ECM enabled be able to come through legibly with ECM
disabled otherwise.
Thanks,
Lee.
