I would like to use an Ubuntu 11.10 workstation as a fax server. What would be the best application to use? How do I configure it to act as both a fax server and fax client? I've tried efax-gtk, but keep running into issues. It mostly seems that the program cannot communicate with the modem. I've tried 3 different internal modems. Do I have to use an external modem via a serial port/com port?
"WinModems" are unlikely to give you any real joy so if you can find a "real" modem (as listed) that should work. Finding one of those might solve your problems with efax.
Edit: Or throw the modems away and use an email->fax service instead.
