"Smallest" Asterisk server? No. That old Gateway box must
be about 2 cubic feet. 1.5 ft^3 at a minimum. I've got one
that is about 0.2 ft^3 a factor of maybe 10 smaller.
I've installed a working Asterisk server on an older Toshiba
notebok PC. The Notebook has a 144Mhz Pentium, 80MB RAM
and a 2GB disk. For very low volume VOIP-only in does OK
Advantages of a Notebook:
1) Very small, no fan, no noise.
2) Comes with built-in battry backup
3) WHat else can you do with a 144Mhz PC?
4) Can run softphone or Asterisk console phone using
built-in sound
Disadvangates
1) How to connect it to the PSTN?
If someone would write a zap driver for the a common PC card
modem (do they still sell these?) then we'd have a realy nice
FXO/VIOP gateway. Most notebook have two PC card slots
I have an _even older_ Notebook can (and this is the good part)
has a docking staion that has a PCI bus) So I'm thinking of
putting the digium card(s) in there. The PC is a 486DX2 at
100Mhz with 16MB RAM. I couldn't get it to work due to the
16MB RAM but after reading the below maybe I'll try again.
