Hi Klaus, Yes, I have learned that both are not to be used. However, I am unable to get the SDP to change with the force_rtp_proxy call. Can you see anything wrong with the way I am calling it? The call is clearly in effect, as it does change the media addresses, just not to what I need them to be. Even if I do specify them explicitly in the call.
