[asterisk-users] Fax and Asterisk

[Andrew Nowrot]

Hi

I am trying to build reliable fax solution with asterisk, iaxmodem and
hylafax. I am attempting to do this on Compaq DL-360 with 2 pentium 3
1.2GHz (512 cache) and 2GB of RAM. I am using a Sangoma A101. After
installing
the newest zaptel and wanpipe-3.1.0 beta I did zttest and it didn't give me
good results:

99.975586% 99.975586% 99.975586% 99.975586% 99.975586% 99.975586% 99.975586%
99.975586% 99.975586% 99.975586% 99.975586% 99.975586% 99.975586% 99.975586%
--- Results after 14 passes ---
Best: 99.975586 -- Worst: 99.975586 -- Average: 99.975586

Sangoma card does not share interrupt with other device.
I am running on Debian lenny with custom  2.6.21.5 kernel with grsec patch.
I configured the kernel with timer frequency of 1000 Hz, with RTC
interrupts, and with enhanced real time clock support.
The question is what else can I do (kernel configuration or any kind of
changing) to improve zttest?
Is it possible to built reliable fax service with this result of zttest?

I ask about the kernel configuration because I notice that each change of
the modules compiled in the kernel improoves the zttest. (some changes
making it worst) At the beginning I had 99.91%, and now after some changes I
am getting 99.9755%.

Cheers

Andrew
