I tried lots of different settings but none really seemed to help.

The line is ISDN BRI with an HFC-S card. Software is bristuff with florz 
patch. Echo can, silence suppr. etc all disabled.

The HP is connected to a Sipura SPA 2000 with the correct settings for fax 
and the region i'm in. Still consistently faxes fail after the first or 
second page. The HP is a LaserJet 3330 mfp.

Setting it back 9600 did help a bit.

I solved the problem now by connecting an old Digital -> Analog converter 
to the BRI line, bypassing Asterisk.

Thanks!
