Cool.  I've been curious to see if anyone has run asterisk on the
IXP425.  Out of curiosity, have you used the HSS interface using the
intel access library to do PSTN interfacing through the SiLabs SLIC?
Also, have you used DSR to do codec accelerations or are you just
letting Asterisk do it native?

Coyote isn't too cheap, but it is meant to be a reference board. There
are several companies who have built mass market solutions that sell
for a lot less on the same architecture.  eg. Netgear's wireless VoIP
box for AT&T Callvantage (retail < $200) but I am not sure if it can
be reprogrammed or not.
