Hello,
from the module readme:
„trust-address - flags that IP address in SDP should be trusted. Starting with rtpengine 3.8, this is the default behaviour. In older versions, without this flag the RTP proxy ignores the address in the SDP and uses source address of the SIP message as media address which is passed to the RTP proxy”
You probably want to change this to SIP-source-address. Refer e.g. to the kamailio default cfg.
Cheers,
Henning

Hi Im using rtpengine_offer as below rtpengine_offer("trust-address replace-origin replace-session-connection ICE=remove") is there another flag I need to set to change c=in to the WAN alias?
rtpeengine.conf interface as set as below ### for different advertised address: interface = 10.3.1.6!20.82.X.X
But the SDP send to client c=IN contains the private IP of the kamailio server
v=0 o=root 321199167 321199167 IN IP4 10.3.1.5 s=Asterisk PBX 18.12.1 c=IN IP4 10.3.1.6 t=0 0 m=audio 32080 RTP/AVP 0 8 103 a=maxptime:150 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:103 telephone-event/8000 a=fmtp:103 0-16 a=sendrecv a=rtcp:32081 a=ptime:20 m=video 0 RTP/AVP 34

Hello,
you might need to set the advertised address for rtpengine as well: https://github.com/sipwise/rtpengine/blob/master/etc/rtpengine.conf
Cheers,

Hi Looking for advise if anyone could point out where im going wrong. My setup is Kamailio Ver 5.6.0 running in azure , rtpengine Version: git-master-dc395d5, behind kamailio I have asterisk ver 18.12.1
Kamailio conf I have interface set as below listen=udp:10.3.1.6:5060 advertise WANIP:5060
and rtpengine.conf set as below interface = eth0/10.3.1.5
but when I can make a call I don’t get any audio, rtpengine.log extract below shows that rtp is going to the private IP rather that the Public IP of the phone that initiated the call, do I need to set rtpengine_manage() to fix this?
