Hi Julian,
Sounds like a frame slip problem if the result depends on the source. Most people, including me, have trouble with the TDM cards. They worked without problem when I was first developing the FAX software in spandsp, so I assume the TDM driver has gathered bugs since that time.
Regards, Steve

Hi Steve,
I sent a mail to this list a week ago regarding exactly this issue. Spandsp doesn't work for me (getting <200rows tiffs), but sending and receiving faxes through a FXS-FXO bridge (a TDM11B) works without problems.
My motherboard is based an Aopen AK33 (VIA686a chipset, KT133, 700Mhz Athlon). I've disabled USB, 2nd IDE, VGA interrupt (runing without X), sound.. I've also tweaked PCI settings in the BIOS, testing each time, but I don't know what can be wrong. Here is some more info:

Why would you expect a bunch of fax modems to work any better than spandsp? If spandsp doesn't work reliably your system is very likely broken.
I have had hundreds of complaints about spandsp reliability. I have analysed at least 50 or 60 audio logs. I have found maybe 5 or 6 which has real spandsp problems. The rest had frame slips. Of the 5 or 6 with real problems, most have been fixed in the latest version. I have one weird audio log from a new HP combination printer and fax machine that i haven't sorted out yet. These HP machines really are total crap. I have workarounds in spandsp for several blatently wrong things they do. I don't yet know who is at fault with this latest problem.
Regards,
Steve
