Asterisk already tries this by default on SIP.  Now on IAX

This would be great but we now have this in chan_iax2.c 

codecpriority=mine   | My pref order is honored.
codecpriority=caller | The callers pref order is honored.

This was just added this past weekend... what we need is a way to tinker
with those pref orders on the fly.
