A small network of 4 phones is simple enough where you can get a low-end
PII box and run Astlinux (http://www.astlinux.org/). I've used AstLinux
before and it works quite well. You can grab their bootable ISO and boot
the machine off of it and run it from there. No hard drive needed.
Astlinux uses a USB flash key to store settings, so that you can use a
read-only bootable CD to boot the machine and then store the settings on
the USB key.
I did a presentation to SFLUG way back on Astlinux. My slides are up at

No. You can mix and match phones, both hardware-based and soft ones. You
can also mix and match protocols such as SIP ans IAX. For example, I
currently have a PBX in my office that allows me to dial out from a
Nokia N810 via Gizmo when I am traveling overseas. Gizmo uses SIP. I am
also able to call home where I have an analog phone connected to an ATA
called the IAXy (http://www.voip-info.org/wiki-IAXy) which uses IAX. The
server (trixbox) translates SIP-IAX on the fly.

Discussion is very appropriate to this list :-)
