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.....


None of my fax machines are able to reduce their TX/RX speeds, if any devices capable of capping the speed it would be a nice addition to the wiki, I would instantly buy some all-in-one machines that could do that

Actually, they are all able to reduce their speed when they need to. They figure out for themselves what the path is capable of. Often in a slightly quirky way, but bugs are the mainstay of the FAX industry.

Indeed but asking HP to implement a cap on the TX/RX speeds is like talking to a brick wall. I guess we will have to look for alternative solutions!
