Correct, but you may find there is no need to go that simple.

Trunking needs timing, but the rest of IAX shouldn't. There are some
other parts of asterisk that would want timing, but you would probably
be removing these for your small footprint.

Well think about what you will have to implement.

1) registration
2) routing
3) config files
4) linking into libiax

Asterisk already has all the above with exception of libiax. I still
feel that by gutting large chunks of the makefile, you will find that
you can strip asterisk down to the bare minimum amount needed to get it
simplified to use on your router.
