You're giving up a lot by using txfax/rxfax instead of HylaFAX for the 
actual fax communication.

Yes, there are ways to use HylaFAX faxq and write your own faxsend that 
will drop .call files into txfax's attention, and I think that there are 
things on Sourceforge to help you do that.  However, I could never bring 
myself to do this.  The sacrifice would have been too great.

Right now Asterisk does not have very good fax support.  So for the most 
part you will not want to pass fax through an Asterisk PBX.  (Like, have 
a separate phone line dedicated for fax.)  That said, you can get 
reliable performance by simply using the Asterisk PBX as a T1 PRI 
"bridge"... meaning you bring your T1 into your multi-port T1 card on 
your Asterisk server, and then you send all fax calls back out through a 
different port which terminates on a T1 faxmodem in your HylaFAX server 
or on a T1 channel bank that is connected to analog faxmodems.

However, I can certainly understand that if you don't use fax very 
often, don't want to use an on-line fax service, don't want to pay for a 
dedicated fax line, and aren't using T1 lines that the options above 
aren't really options at all.  So for that purpose (and *still* not 
wanting to use txfax/rxfax) I've created IAXmodem.  See:  
https://sourceforge.net/projects/iaxmodem  Realize that the first 
release on this was just a week ago, and so I wouldn't say that IAXmodem 
is ready for heavy production use.  However, if you're interested in 
testing, playing around, or maybe just deal with a random fax once in a 
while... well, then maybe IAXmodem will be good to you for now.
