libiax2, chan_iax2 (and their forerunners, libiax and chan_iax) all have 
a common origin, so you'll find that they do many things the same.  
libiax2 is somewhat simpler, and, e.g. always makes explicit ACKs for 
every frame (while chan_iax2 sometimes piggy backs them on other 
frames).  It is somewhat helpful to look at both, though.
