[Asterisk-Users] FAX, IAX and *....Maybe I'm dreaming...:-)

Hi Jeff,
I live in Provo and I think I understand the application you're 
referring to.  Some folks in my neighborhood have been getting to be the 
beta testers for these cool new fiber links that the city is supposed to 
be laying out.  If I only lived a few blocks over, I would be able to 
get one too.  Darn.  Anyway, I've been following this thread, and I'm 
wondering if an alternative might be to provide some sort of fax jack on 
the hardware you provide the customer that your network could notice and 
then treat differently from regular voice data?

An even better alternative would be if asterisk could recognize a fax 
machine on the end of the line and use a different protocol or codec 
that would work with faxes. It sounds like some of the contributors to 
this thread were saying this is possible.  But I'm not sure--I'm pretty 
new to asterisk and VoIP in general, so I could be wrong.
