astfax allows you to create an email to fax gateway. It processes incoming email messages with attached fax images and sends them out via the txfax module. Asterisk's outgoing call queue is used to initiate the fax call and transfer. The call file generated for the outgoing call queue is in template form, and can easily be updated for any system's configuration. It can be used (for example) with qmail, asterisk, spandsp, and eps to create an email/fax gateway.

The communication between client and server is based on a simple ASCII protocol over TCP/IP which should make it easy to develop your own frontend.
