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?

Hello,
you might need to set the advertised address for rtpengine as well:

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 Henning
Issue could be that I’m trying to do something that’s not possible .
We have an asterisk server behind kamailio . kamailio and asterisk are on the same subnet
10.3.1.0/24 . kamailo/rtpeengine are configured to advertise its WAN IP . would this mess
up SIP/RTP from kamailio to the asterisk server.
Best Regards

Hello,
there is no inherent problem regarding SDP handling when Kamailio, rtpengine and e.g.,
Asterisk are on the same subnet. We are running it in some setup on an single machine.

We have an asterisk server behind kamailio . kamailio and asterisk are on the same subnet
10.3.1.0/24 . kamailo/rtpeengine are configured to advertise its WAN IP . would this mess
up SIP/RTP from kamailio to the asterisk server.

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

Hello,
you might need to set the advertised address for rtpengine as well:

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?

Yes.
To make this work, you either need a WAN/NAT setup that is able to
reflect traffic back into the internal network, or (much better)
configure rtpengine with two network interfaces, one with and one
without the advertised address, and then tell rtpengine as part of the
signalling coming from Kamailio which direction the message is flowing.
Use two `direction=` options in the offer with the respective interface
names, and then SDPs going to Asterisk will have the internal address,
and SDPs going outside will have the WAN address.
Cheers

If you have an advertised address configured in rtpengine.conf with the
`!` notation, then this address should be in the outgoing SDP. Double
check that this configuration is actually active and that rtpengine is
actually being engaged for the call.
