	While I have not done extensive testing, Asterisk seems to be quite 
capable on VIA hardware.  I like VIA hardware so much that I compile a 
special AstLinux image for them...

	Why don't you just keep is ulaw and IAX2 trunk in between sites?   That 
would use at most about ~6000kbps with both PRIs at %100. The VIAs could 
definitely handle that.
