[OpenSIPS-Users] Appended media IP when using fix_nated_sdp

[OCEANET - Cédric BASSAGET]

Hi Chen-Che,

I used to have the same problem a few days ago, and I just stoped to use 
fix_nated_sdp.

If you use rtp_proxy_offer and rtp_proxy_answer with correct parameters 
(assuming that rtpproxy works in bridge mode : ei, ie, ee or ii), you 
don't need "fix_nated_sdp" function.

In my environment, it works without fix_nated_sdp and a have a mhomed 
opensips too.

Best regards,
Cédric
