[Freeswitch-users] Faxing with FreeSWITCH

For reference. My test system that I'm trying to build this on is an
old Dell PowerEdge 860 with a single SATA HD, Intel Pentium D 2.8ghz,
and 4GB of ram. It's running CentOS 6.5 and FreeSWITCH 1.2.22. While,
I say "test" it's getting some real use and handling a couple thousend
faxes a month. I know that's not a high volume for some, but it is
working without any load or performance issues. I'm just trying to
adjust it to get the success rate higher :)
I think with my recent change to use fax_detect will help a lot. It's
already sorted a few voice calls out which I verified by listening to
the captured audio in wireshark. "hello... click".
Once I get more done I plan to modify my script so it adjusts per
caller. If it knows the last attempt at 14.4k didn't work, it'll
disable v17 before starting the call, etc, etc. That should help out
some more. Maybe when I get it working smoothly I can post the LUA
somewhere. But then everyone will laugh at my horrible LUA skills!
Having it in lua is really nice (to me) because with FreeSWITCH I can
run a "management" lua script from the console and set routes, and view
logs. I really like that aspect at lot. Might not be ideal for
everyone though.
