[OpenSIPS-Users] Appended media IP when using fix_nated_sdp

Hi all,

I've tried to use rtpproxy_offer("oc", "60.61.x.x") to replace
"rtpproxy_offer() & fix_nated_sdp("10", "61.60.x.x")". However, this is
useful for solving my issue and the RTP proxy even has not received any
command from the SIP proxy server (I tried five times in a row). Besides,
the SDP content of INVITE request with rtpproxy_offer("oc", "60.61.x.x") is
different from that with "rtpproxy_offer() & fix_nated_sdp("10",
"61.60.x.x")". With rtpproxy_offer("oc", "60.61.x.x"), the SDP content of
200 OK has some missing attributes.

Anyone has a solution to my problem that UAs see the "external" interface of
an RTP proxy in the SDP header fields? Any idea is greatly appreciated.

Best regards,
Chen-Che
