<DIV><SPAN class=147321414-11082006><FONT face=Arial color=#0000ff size=2>I run
HylaFAX on a separate box from my dual PRI Asterisk box, and Asterisk relays the
call to HylaFAX when it detects the fax. It relays the call on a private subnet
with a crossover Ethernet cable with the slin codec. I have over 200 IAXmodems
running on the HylaFAX box, which is an underclocked Athlon 64 running CentOS
with a terabyte RAID5 array. HylaFAX automatically converts the fax to PDF and
emails it to the enduser. Mail to fax works fine as well, except my Exchange
server mungs the mimetype so it chokes on attachment conversion from Exchange,
still trying to figure that one out. Fax volume is 100-500 faxes a day from a
couple thousand potential senders, with a reject rate well under 1%. Load
average on the HylaFAX box is usually like 0.01 or 2, with only 256 meg RAM
consumed on the server for HylaFAX, sendmail, the usual suspects running.
Overall, an outstanding solution that was done for a couple grand. Heap praises
on Lee Howard and Steve Underwood for IAXModem and the SpanDSP libraries which
made this possible. (I know they read these lists so I don't mind buttering
their bread) </FONT></SPAN></DIV>

<DIV><SPAN class=147321414-11082006><FONT face=Arial color=#0000ff size=2>One
unusual thing I had to do was to get my reject rate below 1% I had to alter the
Ethernet txqueuelen parameter to 2000 from the stock 1000. Otherwise, works like
a champ and it's a set-it and forget-it solution. It's been up for 6 months now
without a reboot or any maintenance at all (you can afford to be lazy about log
rotation and such when you have a terabyte to play with). Contrast this with our
Windows Zetafax server that requires a weekly reboot plus hand-wringing over
whether to install weekly patches (and we paid $10K, just for the
software). The only thing that keeps me from ditching Zetafax is it has a slick
client that people like to use, unlike the barebones / kooky /
barely-working assortment of clients available for Hylafax (Yes, I looked
at Cypheus. It's crap. Yes I looked at WinHFC. It's good, but
bare-freakin-bones. Yes, I looked at HylaFSP, slick but the wizards would drive
my users insane. They just want to send the fax, dammit, not go through 4 or 5
pages of wizards.)</FONT></SPAN></DIV>
