<div>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.</div>

<div>I'm starting my rtpengine project and I'm facing a strange

<div>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:</div>
<div><br>
</div>
<div>- Remove in the offer the combination of ICE and
replace-session-connection flags</div>
<div>- Switched between rtpengine_offer and rtpengine_manage</div>
<div>- Restarted ngcp-rtpengine-daemon process</div>
<div>- Used sdpops function sdp_remove_line_by_preifx()</div>
<div><br>
</div>
<div>Currently running Kamailio 5.1.2.</div>
<div><br>
</div>
<div>I am running out of ideas.</div>
<div><br>
</div>
<div>Any suggestions would be greatly appreciated.</div>
