Tyler,

Google Talk, Skype, and Gizmo have licensed proprietary CODECs and some 
other technology from Global IP Sound (GIPS).  GIPS has build some 
excellent jitter-resistant technology and do an excellent job of echo 
cancelation and other stuff to make the audio quality at or above the 
PSTN, even on connections that are losey or have high jitter.

iLBC is the GIPS CODEC that they've made available to give people a 
sense of what excellent engineers they are.  Their high bandwidth CODECs 
do the same thing, but with higher quality.

Thanks,

David
