Looks like you're using both rtpengine and some other SDP-modifying
module together, such as nathelper or rtpproxy, without calling
msg_apply_changes() in between.

Hi forum,
I'm starting my rtpengine project and I'm facing a strange problem
with rtpengine. I am seeing this in the SDP part of the INVITE:
a=rtcp:52021
a=rtcp-mux
2001:470:7:3A7:0:0:0:2
a=direction:active
a=oldmediaip:54.153.25.234
As you can see there is a random insert of the local kamailio IP in
there and I'm have tried the following to remove it but failed to succeed:
- Remove in the offer the combination of ICE and
replace-session-connection flags
- Switched between rtpengine_offer and rtpengine_manage
- Restarted ngcp-rtpengine-daemon process
- Used sdpops function sdp_remove_line_by_preifx()
Currently running Kamailio 5.1.2.
I am running out of ideas.
Any suggestions would be greatly appreciated.
