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

Hi Daniel, I have tested using "rtpproxy_manage("", public IP), but in this case, it replaces all the c= lines with this public IP, included c=lines in media descriptions and then, the rtp traffic is not routing to the right IP in MCU. Have I to set up any value/param….to route rtp traffic through rtpproxy in sip server and then it will dispatch RTP packets to MCU? Thanks.

Perhaps fix_nated_sdp(...) can be easily extended to support a list of ip addresses in the second parameter. For now the solution is to use rtpproxy to rewrite all the IP addresses in c= lines with the IP address of the rtpproxy. RTPProxy will then dispatch RTP to the right IP address assigned for each media stream. Regarding the patch sent by Vicente, I just replied on sr-dev mailing list.

I have still not uploaded it to master branch, sorry. May be it is related to your issue, in this link you have the attached patch. http://lists.sip-router.org/pipermail/sr-dev/2012-September/016440.html Kind regards, Vicente.

We are using a SCOPIA 400 MCU to multi-party in a call, and it will set up different IP to send RTP depend on media type. I have tested this function, but it rewrites always all the "c" parameter with the same value. Is there any option to use the function or to rewrite "c" value for each media type independently? Many thanks. Br, Marina ________________________________ Este mensaje se dirige exclusivamente a su destinatario.
