Signalogic sells some hardware cards that utilize Texas Instruments DSPs to perform transcoding. Check out <a href="http://www.signalogic.com/index.pl?page=asterisk_ip_pbx">http://www.signalogic.com/index.pl?page=asterisk_ip_pbx</a>. They supposedly have support for the rtpproxy module in OpenSER, so it makes a good external solution for transcoding. I haven't tried the cards out yet, but I'll post to this list again after we try out an Asterisk/OpenSER configuration.<br>
