A "fax switch" can detect an incoming fax vs voice call. Its purely an inline hardwire gizmo.


but does the gizmo still work if a human answers the phone before the
gizmo?

and how could such a setup work if i want the computer to be both fax
machine and voicemail, on a single phone line, and of course allowing
the humans to answer first if they're available?

it doesn't seem like it should be at all technically difficult, but it
would rely on the modem being able to sense the fax even if it didn't
answer yet.  i haven't actually seen such a setup, but i'd like to..


I have plenty of customers using this set-up under Windows. If the person does not answer the call after X rings, the software takes over to start spewing out a message "You reached the phone/fax machine of <blah>, leave your message after the tone or press start on your fax machine now".


When the sender presses start - a negotiating tone is sent over the line, which the software picks up, kicks into fax mode to receive the fax.

If no tone is heard - the call switched to answering machine mode. A voicemail was recorded. I've even seen multiple mailboxes by asking the sender "press X for <blah>'s mailbox" etc.

Great software. Never seen or heard of it on Linux :(

Also, I've never seen the fax protocol explained, which stopped me from writing my own.

Ed.
