Hmm not so sure of that. I have an HP all-in-one thingy. It is not
possible to set the TX/RX speed hard in the config at a certain
speed. Through the developers menu in the beast it is possible to do
this temporary.
Faxing at max 9600 bps works, anything higher fails miserably after
the second or third page.....
This doesn't make sense. The known problems are all timing related,
and 9600 (I presume you mean V.29 at 9600) is no more or less
sensitive to timing slips than V.17. Actually, on a poor line V.17 at
9600bps should perform considerably better than V.29 at 9600bps. Can
you tell me your exact setup? There must be something else wrong.
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.
The Sipura is probably the problem. FoIP doesn't generally work for a
number of reasons. Packet loss and jitter are just two of them. See
http://www.soft-switch.org/foip.html and
http://www.soft-switch.org/foip-with-real-atas.html for some others.
