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

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.

Hi,
I have similar setup working. I followed these guides : https://saevolgo.blogspot.fi/2013/08/rtpproxy-revisited-kamailio-40.html
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 ?

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 Tomi,
I have noticed that applications such as rtpproxy seem to have instructions for Debian type systems, however, I have found that some applications, like rtpengine, do not play as well with Centos; have you had this same experience? Also, if video is involved, I understood that these proxies are of no benefit. I don’t know this true or not so please correct me if I am mistaken.

Hi Steve,
I have noticed that too thet Debian is used a lot and myself prefer Ubuntu also if I’m asked :) The setup I mentioned is on Suse and all have not went without problems. and currently I have no experience from rtpengine or video. But I am planning to implement WebRTC also so as Sammy mentioned on his reply is the rtpengine way to go with WebRTC. Also have not yet had problems with rtpproxy

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
