Re: [SR-Users] how to use fix_nated_sdp("2") with multiple media types

Hi Daniel, I have tested using "rtpproxy_manage()" before rewritehost(ip public-MCU) and then, in the 200 OK response, using rtpproxy _manage(public ip rtpproxy) and it works. Endpoint sends ftp traffic to MCU through rtpproxy and MCU sends ftp traffic to endpoint through rtpproxy. I am going to update kamailio version too. Many thanks.

So it is a bit of complex routing if you keep it like this. The best is to get it done working with kamailio, rtpproxy and mcu on their public ip, because they have such already. Then you can think of moving to use some private networks. Your fourth bullet below is not clear for me: the clients should have visibility to sip server in order to register and call, but you say not, maybe just a typo. Also, I would recommend to start with latest kamailio 3.3.1 version, 3.2.0 is very old, if you really want that release series, the use latest 3.2.x, not 3.2.0.

Thank you very much.
