Realize if the ITSP does not offer t.38 on the initial invite FS will not find a suitable codec for a fax transaction and off re-invite with t.38. The provider must support re-invite with sdp if they do not send t.38 initially.
IF t.38 is negotiated and the fax still fails, you will get a "ZERO" page email with a TIFF attachment (blank). If it is successful you will get the email as a pdf (assuming you are all patched up). I have tested against more than a few "t.38 compatible" providers, and found many struggled with being able to offer guaranteed routes for t.38 in general, so choose wisely or test thoroughly before you commit.
