I'm using a AVM B1 card. also AVM passive card (FRITZ!PCI) works....
Then is you use SuSe all is configured by yast...



Hello,
probably is a feature what I'm asking for but because of my inexperience to
asterisk this is my question:

I've configured CAPI ISDN to receive calls. When I receive a Fax call, I
expected that asterisk understand it and then launch f (or fax) extension......
Infact, asterisk understand fax machine tone that classically modem shows as
'f'.

But 'f' isn't a real DTMF tone that are 0 to 9, a to d, * and # so
correctly asterisk complain about this.
This causes asterisk not to signal at all the fax call to the dialplan.

Here it is a session viewed from the asterisk's console:

    -- SIP/gs2-eed0 is ringing
    -- SIP/gs2-eed0 answered CAPI[contr1/515387092]/8
