Dont go for "stripped down but complete" distributions which include a
lot of stuff that you dont need, e.g. gcc. Go for a rescue system, like
i used the SuSE rescue system (14 mb), then you can add what you need
(sshd,...) and compile asterisk on another box and then just copy it.
My compressed ramdisk image is 32 mb, including all voice prompts and
some mp3s for MOH.

I just put together the demo system for Linuxtag:
	- Via EPIA 5000 (C3-533), EUR 80,-
	- Morex case with external power supply, EUR 80,-
	- some old 256 mb SDRAMM
	- 128 MB USB memory stick, EUR 30,-
	- 1 quadBRI (could also easily handle an octoBRI, or a PRI card,
	  with the dual riser pci card you can use 2 cards)

The C3-533 is an i586 CPU. According to "show translation" it needs
30 ms for transcoding 1 channel from g711 to gsm (and vice versa).
So, neglecting any overhead caused by channel handling it could
transcode 30 channels to gsm.

Linux BIOS has support for the EPIA boards, so you can speed up booting
very much and also disable the VGA port (very useful for production
deployments....).
