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.
