<div bgcolor="#FFFFFF">Hello,<br>
<br>
you should not set the second parameter of rtpproxy_manage(...), let it be the one returned by rtpproxy.<br>
<br>
And yes, all the occurrences of IP addresses in c= lines will be replaced by the rtpproxy ip, but providing different ports for each media stream.<br>
<br>
Practically the rtp streams are going from end device to rtpproxy and then based on port will be delivered to different IPs of the MCU. Also, the MCU will send from different IPs to RTPProxy on different ports and from there to the end device.<br>
<br>

<div>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. </div>

<div>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?</div>

<div bgcolor="#FFFFFF">Hello,<br>
<br>
I understood that Marina is looking for the option of being able to use different IP addresses for updating various c= lines in SDP.
<br>
<br>
fix_nated_sdp(...) can work only with one IP address given as second parameter (or taken for source address of the packet).<br>
<br>
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.<br>
<br>
Regarding the patch sent by Vicente, I just replied on sr-dev mailing list.<br>
<br>
Cheers,<br>
Daniel<br>

<div class="moz-cite-prefix">Hello Marina,<br>
<br>
there is a bug in sdp parser about c IPs which are not correctly reset for non existent c values in streams.<br>
<br>
I have still not uploaded it to master branch, sorry.<br>
<br>
May be it is related to your issue, in this link you have the attached patch.<br>
