This path will not work. As You mentioned, * supports T38 path through
only. In Your setup there will be a conversion on the * box between T38
via SIP provider and IAX (which uses G711 codec in this case).

To make it work, use newer versions of t38modem and replace the iaxmodem
with it. Newer versions of t38modem supports SIP, so that Your path will
be
PSTN => T.38 aware SIP provider => Internet => My machine (Asterisk) =>
T38-modem on localhost => Hylafax.

HTH,
