I had a question put to me the other day, and it is as follows.
If Asterisk was set up to recieve a line from the PSTN, is it possible that in the event of a fax coming through on that line, Asterisk could detect this and route the call to the fax machine, and if it’s a normal call, route to the telephone?
I’m assuming here that FXO would recieve from the PSTN, then he’d need two FXS, one going to a normal phone and the other to the fax.
If this is possible, are there any issues in doing it?
