Thanks Tomi,
Hope that helps OP as well. Regarding your question: "*when one should use
rtpengine over rtpproxy ?*" I believe its a matter of choice when it comes
to simpler RTP relaying, but once I started working with WebRTC clients
trying to reach Asterisks or FreeSWITCH behind the Kamailio node RTPEngine
played well since it has the capability. I'd recommend comparing the
functions of both on their respective github pages. Mediaproxy on the other
hand doesn't support this Inter-AF bridging at all.
In one particular deployment just like the one discussed over here I tried
RTPengine and it worked but client reported distortion and breaks in voice.
I tried few things but then reverted to rtpproxy and everything went
normal. I switched between the two few times to observe the same
issue. I'm sure I didn't tweak RTPengine, iptables, and OS properly for
RTPengine in that case but, just for sake of comparison, replacing with
rtpproxy brought things to expected behavior. Similarly a different
deployment using RTPengine with WebRTC clients connecting with Asterisks
worked 100% perfectly w/o a hiccup.
Regards,
Sammy

Hi,
I have similar setup working.
I followed these guides :

Maybe you can find those also useful, and if you need more help just let
us know…
I also wonder when one should use rtpengine over rtpproxy ?
BR,
Tomi

To clarify and avoid misleading, rtpproxy should be able to do the same as
rtpengine for this case
Both modules allow to set the public IP address, by providing it as the
second parameter to rtp relay manage function. Also, the applications
themselves have parameters to specify the address to advertise.
Cheers,
Daniel

Morning Arsen
Thanks I’ll take a look at that. Was using RTPProxy just through force of
habit :-)

Hi Mark,
You can solve this by using rtpengine module, it can rewrite SDP offer /
answer and replace media addresses with correct IPs.

Hi all
I’m trying to create a relatively simple setup with Kamailio dual homed
on public/private ip and asterisk on private ip only. The idea is load
balance / fail over asterisk boxes.
Following the real-time tutorial I have clients registering with
Kamailio, Kamailio registering on clients behalf with asterisk as well as
invites going through.
However what I’m seeing is that when an invite occurs asterisk offers
media on its private ip, as it would. However this is making its way
through Kamailio all the way to the client.
After a bit of searching all I can find is people trying to get it
working and failing, or putting asterisk on public IP.
So questions - am I doing this completely the wrong way? Should Kamailio
alter the media ip of asterisk on the way through or do I need to do that
by hand? Surely someone somewhere has a write up on this already :-)
Thanks
Mark
