Hello, besides the authors of that tutorial, is unlikely to find someone to just review the configuration there. In general, there are various cases when one wants to engage rtpproxy, so the way done in that tutorial might not the the only option. It is better to get to the topic from your needs point of view -- like: - do you want to engage rtp proxy only for clients behind NAT? - do you want to engage rtp proxy for all clients/calls?
