<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>
Cheers,<br>

<div>I have tested using "rtpproxy_manage("", public IP),

<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>

there is a bug in sdp parser about c IPs which

I have still not uploaded it to master branch,

May be it is related to your issue, in this link
