It can also happen if another function that alters sdp is used, such as those from rtpproxy or rtpengine modules.

You can execute msg_apply_changes() before/after fix_nated_sdp(), but it is better to find the reason and do only one update of the ip in the sdp.

Might be you are doing fix_nated_sdp, multiple times in configuration.

fix_nated_sdp(10,"1.2.3.4")

But for now it beaks SDP
At the output i see next

c=IN IP4 1.1.1.1
