Hello,
you should not set the second parameter of rtpproxy_manage(...), let it
be the one returned by rtpproxy.
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.
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.
Cheers,
Daniel

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.
Br,
Marina

Subject: Re: [SR-Users] how to use fix_nated_sdp("2") with multiple
media types
Hello,
I understood that Marina is looking for the option of being able to
use different IP addresses for updating various c= lines in SDP.
fix_nated_sdp(...) can work only with one IP address given as second
parameter (or taken for source address of the packet).
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.
Cheers,
Daniel

Hello Marina,
there is a bug in sdp parser about c IPs which are not correctly
reset for non existent c values in streams.
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.

Kind regards,
Vicente.

http://www.tid.es/ES/PAGINAS/disclaimer.aspx Hi,
I have a doubt about how to use "fix_nated_sdp("2")" function when
we have an scenario with multiple media types (audio and video) and
the param "c" in sdp for each media type has a different IP.
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
