IAXModem (and the device you're connecting to) should be sending out the echo 
canceller disable tone (standard tone, I forget the specific standard body # 
it is referenced in) -- I have my fax machines, security system and stamp 
machine work all the time this way, and you can see in the dmesg output that 
the echo canceller for channel 'x' is disabled due to the tone.

Make sure you didn't disable the tone detection in zconfig.h.
