Chapter 8. Fax server

There have many attempts to cleanly integrate Asterisk with faxing, with inconsistent results. For a long time app_rxfax, available at http://www.soft-switch.org/ was the accepted convention. Unfortunately it is error-prone and unreliable. Faxes often arrive piecemeal or worse, not at all.
For that reason, we describe a more robust solution using IAXmodem here (see http://iaxmodem.sourceforge.net/).
