Configure Xp for Automatic FAX recieving - repost

I have a PC that I want to use as a FAX, I want to leave the PC always ON and when a FAX arrives it just print it via predetermintaed printer and store it on a .doc or .pdf file. I also want to have the possibility to send FAXES. You can use XP FAX software or recommend me a better one that you know Its not a complicated job, I have no time to waste on learning how to do it. Thanks
