record the sound fax machines make when negotiating (specifically the part where they try to negotiate anything above 9600 baud) and make a provision in asterisk (an extra letter added to the Dial command?) that will make Asterisk monitor the channel and listen for the fax nego sounds and have Asterisk distort or mute the audio. This way all fax machines
would be forced to lower their speeds.


Complex, clunky, and solves nothing.


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.
