There are actually two reasons. One is that T.38 over IAX is not 
defined. The other is the current T.38 termination support in spandsp is 
only for the full FAX machine it contains. T.38 termination to the class 
1 FAX modem (T.31) interface for HylaFAX is a work in progress. When 
that is done, I hope we will have a sipmodem to replace iaxmodem, 
offering bother audio and T.38 to HylaFAX functionality.
