Rtpengine takes and replaces the entire SDP body, so if there's another
module also manipulating the SDP, one module won't see the changes made
by the other one unless you call msg_apply_changes in between, leaving
you with bits of string in the wrong places.

Thanks Richard.
I do have the nathelper module running but not rtpproxy. How does
nathelper cause this issue?

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.
