Hi,
I have a doubt about how to use "fix_nated_sdp("2")" function when we have an scenario with multiple media types (audio and video) and the param "c" in sdp for each media type has a different IP. We are using a SCOPIA 400 MCU to multi-party in a call, and it will set up different IP to send RTP depend on media type.
I have tested this function, but it rewrites always all the "c" parameter with the same value.
Is there any option to use the function or to rewrite "c" value for each media type independently?
Many thanks.
Br, Marina

Hello Marina,
there is a bug in sdp parser about c IPs which are not correctly reset for non existent c values in streams.
I have still not uploaded it to master branch, sorry.
May be it is related to your issue, in this link you have the attached patch.

Hello,
I understood that Marina is looking for the option of being able to use different IP addresses for updating various c= lines in SDP.
fix_nated_sdp(...) can work only with one IP address given as second parameter (or taken for source address of the packet).
Perhaps fix_nated_sdp(...) can be easily extended to support a list of ip addresses in the second parameter. For now the solution is to use rtpproxy to rewrite all the IP addresses in c= lines with the IP address of the rtpproxy. RTPProxy will then dispatch RTP to the right IP address assigned for each media stream.
Regarding the patch sent by Vicente, I just replied on sr-dev mailing list.
Cheers, Daniel

Hi Daniel,
I have tested using "rtpproxy_manage("", public IP), but in this case, it replaces all the c= lines with this public IP, included c=lines in media descriptions and then, the rtp traffic is not routing to the right IP in MCU.
Have I to set up any value/param….to route rtp traffic through rtpproxy in sip server and then it will dispatch RTP packets to MCU?
Thanks.

Hello,
you should not set the second parameter of rtpproxy_manage(...), let it be the one returned by rtpproxy.
And yes, all the occurrences of IP addresses in c= lines will be replaced by the rtpproxy ip, but providing different ports for each media stream.
Practically the rtp streams are going from end device to rtpproxy and then based on port will be delivered to different IPs of the MCU. Also, the MCU will send from different IPs to RTPProxy on different ports and from there to the end device.
Cheers, Daniel

Hi Daniel,
Thanks. But, I think there is any think I have not understand. I have my route[MCU] module with the following code:
route [MCU]{ if (uri=~"^sip:[7,8][0-9]+@"){ xlog("Forward to MCU"); rewritehost("10.95.94.142"); rewriteport("5070"); rtpproxy_manage(); t_relay(); t_on_reply("CHANGE_SDP"); xlog("after forward to MCU"); exit; }
}
onreply_route[CHANGE_SDP] { xlog("CHANGE_SDP");
if(t_check_status("(200)|(183)")) { if(has_body("application/sdp")) { if(search("IN IP4 10.95.94.142")) { xlog("search IN IP4 .142"); fix_nated_sdp("2", "195.235.93.8"); //where 195.235.93.8 -->public IP of sip server with rtpproxy }
} }
}
If I comment t_on_reply("CHANGE_SDP") line, I can observe traffic from MCU to rtpproxy is received (testing using tcpdump), but traffic from endpoint to rtpproxy is not received and therefore, input traffic MCU is null. In this case, using only: rtpproxy_manage(), the IP in SDP are not replaced by rtpproxy IP.
If I don't comment t_on_reply("CHANGE_SDP"), in this case, I force to replace IP using "fix_nated_sdp("2", publicIP)" and I can observe using tcpdump in server than traffic from endpoint from rtpproxy is received, but traffic from rtpproxy to MCU is not received and traffic from MCU to rtpproxy is not received.
My question is, how can I set up using "rtpproxy_manage(),…."to allow all there traffic will be routed rightly through rtpproxy? Should I add any new line in my config file? Anything to change?
Many thanks.

Hello,
you should not set the second parameter of rtpproxy_manage(...), let it be the one returned by rtpproxy.
And yes, all the occurrences of IP addresses in c= lines will be replaced by the rtpproxy ip, but providing different ports for each media stream.
Practically the rtp streams are going from end device to rtpproxy and then based on port will be delivered to different IPs of the MCU. Also, the MCU will send from different IPs to RTPProxy on different ports and from there to the end device.
Cheers, Daniel

Hello,
I understood that Marina is looking for the option of being able to use different IP addresses for updating various c= lines in SDP.
fix_nated_sdp(...) can work only with one IP address given as second parameter (or taken for source address of the packet).
Perhaps fix_nated_sdp(...) can be easily extended to support a list of ip addresses in the second parameter. For now the solution is to use rtpproxy to rewrite all the IP addresses in c= lines with the IP address of the rtpproxy. RTPProxy will then dispatch RTP to the right IP address assigned for each media stream.
Regarding the patch sent by Vicente, I just replied on sr-dev mailing list.

I have tested this function, but it rewrites always all the "c" parameter with the same value.
Is there any option to use the function or to rewrite "c" value for each media type independently?

Hi Daniel,
I'm sorry, but the traffic between rtpproxy and MCU and from MCU to rtpproxy is not received.
I have used "rtpproxy_manage()" in onreply_route[ ]…and I can observe traffic from endpoint to RTPPROXY is sent and received but, from rtpproxy to MCU and from MCU to rtpproxy I cannot receive any traffic. Is it possible RTPPROXY don't know where must send traffic to MCU?
Many thanks.

} }
}
If I comment t_on_reply("CHANGE_SDP") line, I can observe traffic from MCU to rtpproxy is received (testing using tcpdump), but traffic from endpoint to rtpproxy is not received and therefore, input traffic MCU is null. In this case, using only: rtpproxy_manage(), the IP in SDP are not replaced by rtpproxy IP.
If I don't comment t_on_reply("CHANGE_SDP"), in this case, I force to replace IP using "fix_nated_sdp("2", publicIP)" and I can observe using tcpdump in server than traffic from endpoint from rtpproxy is received, but traffic from rtpproxy to MCU is not received and traffic from MCU to rtpproxy is not received.
My question is, how can I set up using "rtpproxy_manage(),…."to allow all there traffic will be routed rightly through rtpproxy? Should I add any new line in my config file? Anything to change?
Many thanks.

Hello,
from the trace it seems that mcu is on a private network. Also, rtpproxy seems to be configured to listen on a private address. But then the response is sent to a public address.
First, is the routing between the two networks configured on the server where kamailio/rtpproxy runs? rtproxy should be on public interface to be able to talk with the clients on the public network.
Then, with rtpproxy, each side has to send a packet in order to know where to send the packets. Does MCU send packets? If not you can try to add flag 'r' for messages coming from it.
If the networks are not interconnected at ip layer, then you should use rtpproxy in bridge mode. That requires more flags to rtpproxy_manage() parameter as well as extra command line parameter for rtpproxy application.
One example of doing bridging with kamailio and rtpproxy is presented in the tutorial: - http://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6
Should give a better view of how to do it, practically you have to listen on a second ipv4 address instead of ipv6.
For the future, if you give the ngrep, give also the INVITE requests along with the 200ok, in that way we can spot what is wrong with the call better.
Cheers, Daniel

Hi Daniel,
I'm sorry, but the traffic between rtpproxy and MCU and from MCU to rtpproxy is not received.
I have used "rtpproxy_manage()" in onreply_route[ ]…and I can observe traffic from endpoint to RTPPROXY is sent and received but, from rtpproxy to MCU and from MCU to rtpproxy I cannot receive any traffic. Is it possible RTPPROXY don't know where must send traffic to MCU?
Many thanks.

Hi Daniel,

} }
}
If I comment t_on_reply("CHANGE_SDP") line, I can observe traffic from MCU to rtpproxy is received (testing using tcpdump), but traffic from endpoint to rtpproxy is not received and therefore, input traffic MCU is null. In this case, using only: rtpproxy_manage(),* the IP in SDP are not replaced by rtpproxy IP.*
If I don't comment t_on_reply("CHANGE_SDP"), in this case, I force to replace IP using "fix_nated_sdp("2", publicIP)" and I can observe using tcpdump in server than traffic from endpoint from rtpproxy is received, but traffic from rtpproxy to MCU is not received and traffic from MCU to rtpproxy is not received.
My question is, how can I set up using "rtpproxy_manage(),…."to allow all there traffic will be routed rightly through rtpproxy? Should I add any new line in my config file? Anything to change?
Many thanks.

Hello,
you should not set the second parameter of rtpproxy_manage(...), let it be the one returned by rtpproxy.
And yes, all the occurrences of IP addresses in c= lines will be replaced by the rtpproxy ip, but providing different ports for each media stream.
Practically the rtp streams are going from end device to rtpproxy and then based on port will be delivered to different IPs of the MCU. Also, the MCU will send from different IPs to RTPProxy on different ports and from there to the end device.
Cheers, Daniel

Hi Daniel,
I have tested using "rtpproxy_manage("", public IP), but in this case, it replaces all the c= lines with this public IP, included c=lines in media descriptions and then, the rtp traffic is not routing to the right IP in MCU.
Have I to set up any value/param….to route rtp traffic through rtpproxy in sip server and then it will dispatch RTP packets to MCU?
Thanks.

Hello,
I understood that Marina is looking for the option of being able to use different IP addresses for updating various c= lines in SDP.
fix_nated_sdp(...) can work only with one IP address given as second parameter (or taken for source address of the packet).
Perhaps fix_nated_sdp(...) can be easily extended to support a list of ip addresses in the second parameter. For now the solution is to use rtpproxy to rewrite all the IP addresses in c= lines with the IP address of the rtpproxy. RTPProxy will then dispatch RTP to the right IP address assigned for each media stream.
Regarding the patch sent by Vicente, I just replied on sr-dev mailing list.
Cheers, Daniel

Hi,
I have a doubt about how to use "fix_nated_sdp("2")" function when we have an scenario with multiple media types (audio and video) and the param "c" in sdp for each media type has a different IP. We are using a SCOPIA 400 MCU to multi-party in a call, and it will set up different IP to send RTP depend on media type.
I have tested this function, but it rewrites always all the "c" parameter with the same value.
Is there any option to use the function or to rewrite "c" value for each media type independently?
Many thanks.

Hi Daniel:
The network is:
* MCU is running in a private network with IP's (10.95.94.142 and 10.95.94.143) and public IP's 195.235.93.166 and 195.235.93.161. * SIP server and rtpproxy are running in another network: 10.95.94.92, with public IP: 195.235.93.8. * SIP server, rtpproxy and MCU has visibility between them. * Clients have not visibility with sip server and MCU, and they try register, invite,….using the public IP: 195.235.93.8 (public IP of rtpproxy) * When I have not use MCU, only 2 participants, the video and audio is routing OK. * I can verify using web browser conference in MCU that it is sending RTP traffic (out traffic).
Thank you very much.

Hello,
from the trace it seems that mcu is on a private network. Also, rtpproxy seems to be configured to listen on a private address. But then the response is sent to a public address.
First, is the routing between the two networks configured on the server where kamailio/rtpproxy runs? rtproxy should be on public interface to be able to talk with the clients on the public network.
Then, with rtpproxy, each side has to send a packet in order to know where to send the packets. Does MCU send packets? If not you can try to add flag 'r' for messages coming from it.
If the networks are not interconnected at ip layer, then you should use rtpproxy in bridge mode. That requires more flags to rtpproxy_manage() parameter as well as extra command line parameter for rtpproxy application.
One example of doing bridging with kamailio and rtpproxy is presented in the tutorial: - http://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6
Should give a better view of how to do it, practically you have to listen on a second ipv4 address instead of ipv6.
For the future, if you give the ngrep, give also the INVITE requests along with the 200ok, in that way we can spot what is wrong with the call better.
Cheers, Daniel

I'm sorry, but the traffic between rtpproxy and MCU and from MCU to rtpproxy is not received.
I have used "rtpproxy_manage()" in onreply_route[ ]…and I can observe traffic from endpoint to RTPPROXY is sent and received but, from rtpproxy to MCU and from MCU to rtpproxy I cannot receive any traffic. Is it possible RTPPROXY don't know where must send traffic to MCU?
Many thanks.

} }
}
If I comment t_on_reply("CHANGE_SDP") line, I can observe traffic from MCU to rtpproxy is received (testing using tcpdump), but traffic from endpoint to rtpproxy is not received and therefore, input traffic MCU is null. In this case, using only: rtpproxy_manage(), the IP in SDP are not replaced by rtpproxy IP.
If I don't comment t_on_reply("CHANGE_SDP"), in this case, I force to replace IP using "fix_nated_sdp("2", publicIP)" and I can observe using tcpdump in server than traffic from endpoint from rtpproxy is received, but traffic from rtpproxy to MCU is not received and traffic from MCU to rtpproxy is not received.
My question is, how can I set up using "rtpproxy_manage(),…."to allow all there traffic will be routed rightly through rtpproxy? Should I add any new line in my config file? Anything to change?
Many thanks.

Hello,
you should not set the second parameter of rtpproxy_manage(...), let it be the one returned by rtpproxy.
And yes, all the occurrences of IP addresses in c= lines will be replaced by the rtpproxy ip, but providing different ports for each media stream.
Practically the rtp streams are going from end device to rtpproxy and then based on port will be delivered to different IPs of the MCU. Also, the MCU will send from different IPs to RTPProxy on different ports and from there to the end device.
Cheers, Daniel

Hello,
I understood that Marina is looking for the option of being able to use different IP addresses for updating various c= lines in SDP.
fix_nated_sdp(...) can work only with one IP address given as second parameter (or taken for source address of the packet).
Perhaps fix_nated_sdp(...) can be easily extended to support a list of ip addresses in the second parameter. For now the solution is to use rtpproxy to rewrite all the IP addresses in c= lines with the IP address of the rtpproxy. RTPProxy will then dispatch RTP to the right IP address assigned for each media stream.
Regarding the patch sent by Vicente, I just replied on sr-dev mailing list.
Cheers, Daniel

there is a bug in sdp parser about c IPs which are not correctly reset for non existent c values in streams.
I have still not uploaded it to master branch, sorry.
May be it is related to your issue, in this link you have the attached patch.

Kind regards, Vicente.

I have a doubt about how to use "fix_nated_sdp("2")" function when we have an scenario with multiple media types (audio and video) and the param "c" in sdp for each media type has a different IP. We are using a SCOPIA 400 MCU to multi-party in a call, and it will set up different IP to send RTP depend on media type.
I have tested this function, but it rewrites always all the "c" parameter with the same value.
Is there any option to use the function or to rewrite "c" value for each media type independently?
Many thanks.
Br, Marina

Hello,
the signaling shows traffic going from public IP (caller) to private IP (kamailio) then back to public IP (callee). So it is a bit of complex routing if you keep it like this. The best is to get it done working with kamailio, rtpproxy and mcu on their public ip, because they have such already. Then you can think of moving to use some private networks.
Your fourth bullet below is not clear for me: the clients should have visibility to sip server in order to register and call, but you say not, maybe just a typo.
Also, I would recommend to start with latest kamailio 3.3.1 version, 3.2.0 is very old, if you really want that release series, the use latest 3.2.x, not 3.2.0.
Cheers, Daniel

Hi Daniel:
The network is:
- MCU is running in a private network with IP's (10.95.94.142 and 10.95.94.143) and public IP's 195.235.93.166 and 195.235.93.161.
- SIP server and rtpproxy are running in another network: 10.95.94.92, with public IP: 195.235.93.8.
- SIP server, rtpproxy and MCU has visibility between them.
- Clients have not visibility with sip server and MCU, and they try register, invite,….using the public IP: 195.235.93.8 (public IP of rtpproxy)
- When I have not use MCU, only 2 participants, the video and audio is routing OK.
- I can verify using web browser conference in MCU that it is sending RTP traffic (out traffic).
Thank you very much.
Br, Marina
I attach the sip messages of a call with/without MCU:

Hi Daniel, I have tested using "rtpproxy_manage()" before rewritehost(ip public-MCU) and then, in the 200 OK response, using rtpproxy _manage(public ip rtpproxy) and it works. Endpoint sends ftp traffic to MCU through rtpproxy and MCU sends ftp traffic to endpoint through rtpproxy. I am going to update kamailio version too.
Many thanks.
