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%.

Rumor is it that the Sangoma hardware isn't as needy this way as is the Diguim. I'm not sure about that, though. In any case, what does your /proc/interrupts file say? My guess is that your A101 is coming after something, like your hard drive interface or your LAN interface or something. Lee.

The timing should come from the card, and not from ztdummy. Make sure that the timing comes from the card and not from ztdummy. Small slightly off-topic plug: Is the following extra text added to the Zaptel README of any use to explain a bit about the Zaptel timing source? http://svn.digium.com/view/zaptel/branches/1.4/README?r1=2703&r2=2702&pathrev=2703> 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?What is the target of the fax?
