Fax/message solutions

I had a Win95/98 box that was my fax / voice message machine. Once a
call came in, the Caller ID info used to page me a long time ago, (I
could retreive the message/faxes form anywhere) then I was able to put
that info on a web server running from my house a few years ago.

My web server is running IIS5 which is sitting ay my ISP colo space
right now. All this happened on the East Coast. I got fed up with a
lot of things (Microsoft included), packed up and headed West of the
Pecos (here in AZ). I close on my house in 7 days.

My goal is to convert my web server to Linux/Apache. Easy

I need to know if anyone is using a Linux based solutions for Fax/Voice
messaging that will do the same as my Windows box.

As soon as I get a static IP address, I'll be calling for my web server.
