When using t38modem faxgetty will make no distinction between that 
device/connection and any other device or connection.  faxgetty speaks 
T.31 to the modem, and uses T.30 to know what to speak.  (I.e. the 
sentence structure is T.30, but the words are T.31.)

t38modem will perform T.38 entirely transparent to faxgetty.

Since T.38 is not supported by IAX2 there really is no way to "add" T.38 
support to iaxmodem without pretty much ripping out nearly all that is 
iaxmodem... you'd end up with a scrap of stuff... a pseudo-device 
handler and a worthless loop... and after building in what would need to 
be there the end result would be "sipmodem" or "h323modem"... both of 
which already exist in t38modem.

Thanks,

Lee.
