I'll be a little more constructive than that. I've never done it the
way you're trying to do it, and don't know whether it will work. I
will say that I dis-recommend trying to test faxing, or even SIP in
loopback mode. My experience is that debugging is more fruitful when
you have two systems you can control, and this applies specifically to
faxing where you want to be able to watch the sender and receiver
separately. If you can disentangle the logs in real-time, more power
to you. Fire up a virt if you don't have a second machine you can
control.

Now for the part I do know something about. Native asterisk fax
support and native asterisk sip support improved in 1.6. With 1.6
there is a built-in app_fax module which works quite well for sending
fax over SIP with T.38. I found the configuration and debugging
simpler and more understandable. I never really knew why my
asterisk-1.4 faxing experiments went so badly, and I had no reason to
go find out once my asterisk-1.6 faxing worked so well.

I will say as an opinion:
Openh323 + ptlib_unix + t38modem + hylafax + asterisk-1.4

sounds like a lot harder to troubleshoot than:
asterisk-1.6 with app_fax built-in

Try 1.6. You'll be glad you did.
