I have a lot of installations using this board:

   http://www.icp-epia.co.uk/index.php?act=viewProd&productId=90

The key thing is to compile asterisk for a i586. This is vitally 
important, as the VIA processor on those boards is lacking some MMX 
instructions that asterisk uses.

20 calls aren't an issue here. Transcoding is. You *really* don't want to 
be using speex or ilbc here!

Here is the output of a show translation recalc 30 on one of these:
