AFAIK it's the digium card that _detects_ the fax, and allows the call 
to jump to the 'fax' extension.  So fax _detection_ is a function of 
the card/driver .. and using the 'fax' extension requires the use of a 
digium card.

SpanDSP just talks fax .. I don't think it actually does any detection.
