I _want_ FSK. A few ast_debug's in chan_dahdi tell me that after calling vmwi_generate(), it's taking the MWI_SEND_SPILL path through mwi_send_thread(), and happily sending about 9K bytes of spill, 160 bytes at a time. But my phones (and a butt-set) tell me that nothing is being received.
I don't understand the DAHDI ioctls very well. Is it possible that the TDM840 is not in the correct state when the spill is transmitted?
