[Freeswitch-users] Hylafax server emulation

[Pablo Hernan Saro]

I don't proclaim myself the best telephony engineer in the world, so I'm
free to go wrong and open to learn. You can consider my contribution the
most bizarre solution you've seen in a long time, we're all free to think
and speak whatever we want (this is beyond discussion). IMHO, it is a simple
way to integrate HylaFAX and FS without programming a line of code. SIP and
t38 is out there to be used, in fact AFAIK all SIP trunk service providers
offer fax support this way. Why you believe it's the most bizarre solution?

PS: I do not want to challenge you, just want to feed my knowledge.
