You don't say what's between the boxes as the medium over which the
faxes are going.

Try a fax between them without t.38 and see if it goes through. It
might be a connection that is not reliable for any kind of faxing.

That would not be an asterisk problem, it would be a faxing over a bad
connection problem.
