I have a working (well, almost :D) setup of Trixbox CE 2.4 with IAXmodems running on the same machine, using SLIN codec. My Hylafax + Avantfax is on another machine (virtual machine located on a physical machine different from Trixbox) communicating by interceptty. We receive faxes on ISDN lines, my Trixbox machine is equipped with Sangoma A500D card.
Problem is, that 4 of 5 received faxes get corrupted. It looks like they get squisshed badly.

Any ideas?
Moderator is asked to remove this topic. I have traced problems with channel jitter (ZTTEST showing 99.96% and lower) so my question is not valid now.
Thanks for following up on this. I will leave it here for others to see as it may help them with the same problems.
Then again... I was too eager with my assumptions.
It turns out (at least that's what Sangoma support says), that zttest results are not meaningfull for Sangoma A500D. I will have to find another reason, why some (like 60%) of incoming faxes fail.
I have checked, that sending faxes between my IAXmodems works fine. I do not understand, why faxes received over ISDN BRI -> Sangoma A500D -> Asterisk would fail. If I understand right, there is no possibility of weak signall issue. The only thing I could imagine as a cause of my problems is timing.
Could anyone explain me, how IAXmodem is synchronized with A500D and Asterisk? Do I get timing from ISDN line or A500D has its own timer?
My setup is:
Core2Duo
Intel chipset MB
1Gig ram
raid 1 setup with 2 IDE drives
Sangoma A500D PCI card with 3 BRI modules, latest drivers
100Mbit ethernet for WAN
1000Mbit ethernet for LAN
Trixbox 2.4 CE
Another thought: dual cores causing some problems?
Looking forward to any replies...
zttest is meaningful, but not entirely meaningful. It has meaning, but not nearly as much as we would like it to have.
Make an audio recording of a fax call using the "record" feature (see README). Then send the recording to to me at faxguy@howardsilvan.com.
Problem solved. I have found out, that running ztcfg -vvv from CLI helps. I don't really understand the mechanism, but it seems that zaptel dummy device is unable to get stable clock source during system startup. If I run it later, my zttest results are fine. What worries me is the fact, that sometimes it takes two ztcfg runs before zttest starts showing 99.99% results.
My current zttest results are:

IAXmodem now works like a charm and I am finally happy with Hyla and Avanfax.
Now if only fax detection worked better :)
