Just curious why to you need fax detection on outbound calls?

I think it is possible to set up Hylafax to fax straight from an
extension.
All you need I think is an outside dial tone.  So if I plan to send a
fax I would dial, for example "9,," to get an outside dial tone, is it
it how it works?
the comma "," after the number causes 2sec. pause so tow commas = 4sec.
causes this should be enough time to get an outside dial none and the
rest is simple, just let the Hylafax dial all the numbers.
