<div>Hi Daniel,</div>
<div><br>
</div>
<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><br>
</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><br>
</div>
<div>Thanks.</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>
