Hi,

The fax detection in chan_capi use the CAPI DTMF feature. So you need to set
in /etc/asterisk/capi.conf the line softdtmf=0
Check if CFLAGS+=-DFORCE_SOFTWARE_DTMF in Makefile of chan_capi is commented
(#).
If you start asterisk with the -vvvvv option, you should see :
CAPI[contrX] supports DTMF

And obviously the card must report a DTMF when a fax tone is detected.

It may be possible to alter the code and use the asterisk dsp code instead.

Regards,
