Help installing SipX 3.8 on fedora 7

Hi to all,

I am new to Linux and SipX, but I am willing to learn, I have installed the Fedora 7 and I want to know if I can install the SipX 3.8. I don't want to install the SipX from the ISO because I don't want my hardisk to formatted again because when I tried to boot the CD ISO of SipX it tells that it will erase all the data in my HD. What I want is to install SipX on my readily installed Fedora 7. Can anyone give me a step by step guide on how can I do it? Thanks for those so will respond to my questions.
