Since no one else has responded I'll chime in with some general advice.
It's troubling to see that your "provider" is using Asterisk to face
you (the customer).
I've never had any luck getting T.38 to work (at all, in any mode)
using Asterisk. I've heard of other people making it work but
consider the chain here:
Their provider (they appear to be using DIDx, hmmm) -> Callwithus
(using Asterisk) -> You (FreeSWITCH) -> Your device
I don't see anything specific in your case but there are many, many
places for T.38 to go wrong in this scenario. I'd recommend
attempting T.38 against a local gateway or known Tier 1 provider
supporting T.38 with known equipment.
Otherwise, do you have any updates for us?
