[SR-Users] kamailio & rtpengine question

[Gerry Kernan]

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

Best Regards

Gerry

Hello, you might need to set the advertised address for rtpengine as well: https://github.com/sipwise/rtpengine/blob/mas͏​​‌͏

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?
