Many users don't realize that faxing is a function that can only use analog
phone lines and analog fax modems.
....or G3 analog fax emulation over ISDN - such as provided with most, if not
all, commercially available ISDN TAs. Pop over here
http://www.billion.com/communication/communication.html and you should find
suitable software/drivers for your TA
Oh - BTW, there is also G4 Fax, which is explicitly an ISDN fax standard
With some ISDN lines you can isolate the
voice/analog line and hook that directly to your analog modem or obtain a
line filter suitable for connecting a standard analog voice line then
connect an analog fax modem to that line.
Er..I think you are confusing ISDN with ADSL. Pretty much all voice and fax
traffic has been carried over ISDN for the past 20 years - it is just that
the local access (or subscriber line) is analog - with the D/A conversion
taking place at the local exchange.
The solutions you are referring to apply to ADSL - there is no analog
carrier in an ISDN line, so there is nothing to isolate or filter.
