Interesting. Thanks for the tidbit. I will play around with
msg_apply_changes and find the right place for it.

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.
Cheers

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.
