Wow! The crew working on Freeswitch are certainly pushing forward. Michael Collins just post a notice of the availability of v1.0.3 which includes 127 fixes & changes. A couple of the more interesting include leveraging the Digium TC400B hardware for multi-channel G.729a and G.723.1 transcoding, also AMR-WB passthough.
Kristian K of Star2Star and Astlinux fame has also worked to make Freeswitch compile within the Astlinux development environment. So you can have a high-performance SIP proxy and Asterisk running on small format embedded hardware. OMG, I love that!
Since Freeswitch is now an installable module for pfsense you could also have it running on your router. That’s great, too!
