First off, I'm not really the right guy to be having this conversation, 
but since I know enough of the facts I can respond accurately enough to 
satisfy your query.  If you ask a lot more questions in the "what-if" 
direction I may have to bow out.

Steve's related code is two-fold... code that is in spandsp and code 
that is in OpenPBX.  And, actually I think that spandsp comes with 
OpenPBX, so it's really just one download.

Anyway, spandsp is a library.  You get it, install it, and you end up 
with a bunch of code libraries that really don't do anything by 
themselves.  You have to have some other software that utilizes those 
libraries, like the well-known txfax and rxfax applications... or like 
iaxmodem.

Steve's work in OpenPBX is not really something that you can extract out 
of OpenPBX and stick into Asterisk very easily.  I guess you're welcome 
to try, though.  And, if you become successful in that - in producing a 
patch to apply onto Asterisk and you then endeavor to maintain that 
patch along with all of the other patches that you have to maintain to 
keep your motley Asterisk running your OpenVOX cards, your txfax/rxfax 
apps, and the myriad of other things that don't come with Asterisk for 
who-knows-what reason... well, then you're effectively maintaining your 
own little fork of Asterisk.  And at that point I would wonder why you 
have gone through all of that effort just to avoid using OpenPBX, which 
is where  Steve put that code for you to use in the first place.
