[OpenSIPS-Users] fix_nated_sdp and rtpproxy

[Yury Kirsanov]

Hi,
I have a problem with remote client who can't properly configure NAT and is
sending private IP in all SDP and SIP packets. I've resolved issues with
registration but can't resolve the issue with SDP. My topology is as
following:

<Client> ----- <NAT router> ------- <RTP Proxy> ---------- <OpenSIPS>
-------- <NAT> ----------- <PBX>

So, I need to simultaneously engage RTP Proxy to bridge external Internet
and our local LAN and need to rewrite SDP body of original Client's packet
with received IP address. If I'm doing fix_nated_sdp and then
rtpproxy_offer - I'm getting doubled IPs in SDP message, like this:

100.11.100.200192.168.20.200


Is there any way to update SDP of client's packet and then command RTP
Proxy to use updated IP? Thanks!
