RES: [Asterisk-Users] Fax detection & CAPI (doesn't work!)

[Humberto Aicardi]

Hi,

	Thanks for the reply, what I currently have is the chan_0.3.5 with
the CVS HEAD and fax patch applied. I have made all combinations possible
with softdtmf=0/1 and enabling/disabled FORCE_SOFTWARE_DTMF and nothing.
During the loading process of the capi channel driver I get a " CAPI[contrX]
supports DTMF" but still the extension for fax does not get executed, any
toughts?

Regards,
Humberto Aicardi

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,
