The only thing I can think of that would be preventing the output would be problems in the interface chip with the On-Hook transfer mode. If you run a dahdi_monitor on the channel that should be sending the FSK spill and look at the results in a program like audacity, you can see if the MWI FSK spill is actually reaching the interface SLIC IC. Something like "dahdi_monitor 1 -t spilloutput.raw" (Monitors the output going to dahdi channel 1.) > I don't understand the DAHDI ioctls very well.
