[asterisk-users] Using Asterisk as an Fax-Gateway for analog Fax devices

I have been trying to do this.  The only thing, really holding me up is 
IAXmodem 1.0 rpm for Centos5.  Anyone want to build it for me (I am 
terrible at compiling; do it maybe once a year).

First off, if you are NOT using T38 between Asterisk and the ATA, there 
cannot be any packet loss or reordering between Asterisk and the ATA.  
T30 is fragile over RTP.  But I do this very well by having them on the 
same LAN.

One of the big challenges is a SENDMAIL one.  What is the fax 
extension?  Fax#@asterisk.foo.com is easy and I have done this.  
User at fax.asterisk.foo.com is REALLY hard and actually violates a couple 
of the DNS and SMTP RFCs (a don't do this anymore SHOULD NOT).  Lee 
Howard believes some of my naming problems are fixed in Hylafax+ and 
that is what I will test with once I get that IAXmodem rpm (and T38modem 
rpm too!  Please!).

Scalix is what I run here.  The right DNS magic and Scalix will forward 
the mail to user at fax#.asterisk.foo.com.  fax#@asterisk.foo.com only 
takes a DNS A record (NOT an MX or CNAME RR).

Give me a hand with the Centos 5 (RHEL5 of FC6) rpms and you got a partner.

BTW, I am running Trixbox 2.4.  I have a really simple custom dialplan 
for fax to email.  Works like a charm.  No GUI front end for entering 
the fax# extension to email mapping.  I do that with SSH and VI....  
Will not support T.38 (need Hylafax and T38modem for the T38 gatewaying).
