I am trying to setup fax for my Desktop. In my kernel, i have support for modem and fax. But, I am not able to send fax
I want a procedure to get fax done with my machine.
Can anyone help me with the requirements?

Have you searched on Google for that?

Trying searching for "fax on fedora" on google.

Try out the Adminsparadise Voip PBX and Fax software
Free!!!

There is a livecd for preview and an installation cd that automates the install for you.

The web based fax allows you to preview incoming and outgoing faxes via thumbnails on a web page.
It also automagically installs sambafax, hylafax, avantfax.

winprinthylafax will allow you to fax directly from your desktop..

Avantfax has been tweaked so that not only can you do the standard pdf and tiff but also upload practically all word,excel formats..

save yourself the time and trouble.
