Hello,

I have the following configuration :
E100P -> * -> TDM400 -> Modem

When I receive FAXes, about 20% of them are corrupted : pages are not always
complete. If the fax is complex or with numerous pages, it's usually a mess.

Before that, I was using spandsp with success. Unfortunately it's too picky
with some broken fax (training failed).
Since this failure only occurs with the same set of faxes and it's
reproducible, I'm confident about my E100P configuration.

That's why I suspect frame slips on the TDM400 side.

How can I solve this issue ?

It's a dual p3, highly idle without IRQ sharing :
 20:  602869735  602487558   IO-APIC-level  wctdm
 21:  602485799  602863515   IO-APIC-level  t1xxp

zaptel.conf :
span=1,1,0,ccs,hdb3,crc4
bchan=1-15,17-31
dchan=16
fxoks=32-35

zapata.conf :
