[Freeswitch-users] Codec order flipped in proxy-media mode re-INVITE

[Jeff Pyle]

This seems to break other things.  I lose media, possibly when the far end
sends 200 OK.  I didn't have an opportunity to do much troubleshooting.

I'm working a different approach that includes removing FS from the media
path altogether.
