Are you using a single credential-tuple with the provider?

If the provider supports T.38 and if you can separate out fax lines,
there is no need to stick asterisk between them and t38modem.  Just have
t38modem access the provider directly.  Hylafax will handle the rest.

(Look for things like sub-account, peer and/or trunk configs.)
