I got my hylafax running to receive and send fax. Since I only have one

phone? Is it something that can be done?

If coming in on a Zap channel, then:
In /etc/zapata.conf in the relevant channel definition you need:
faxdetect=incoming
Then in the dialplan you need to answer the incoming call (as you've no
other way of telling if it's a FAX calling), and listen in for a second or
2 (with a Wait(2) instruction), then if it's an incoming FAX, asterisk
will jump to the fax extension, then you can Dial the hylafax extension,
etc.
Or if it's not a fax, at this point the caller is now paying for the call,
because you've answered it, so be nice to them - play a message, ring the
phones, etc.
Personally, for a simple installation like this, I'd install spandsp,
rxfax & txfax and not use hylafax, but if hylafax is something you're used
to then go that route...
