There has been several updates to iax on Head cvs and one bug fix last week
to Stable. I've got multiple iax2 connections with various customers and
providers, and I firmly believe there are more bugs to be addressed.

Choppy audio seems to the norm for cisco 7960 users for a number of 
different reasons including what is believed to be a cisco sip v6.x
problem. I've personally invested a significant amount of time trying
to diagnose the symptoms with a packet analyzer, and I can "see" many
of the issues, but don't have the programming skills to bring those
observations back into code. But, I'm not giving up and will continue
to help document the specifics so those with the skills can address
the issues.
