[OpenSIPS-Users] Does Media_Relay component implies in impossible direct media?

[Rodrigo Pimenta Carvalho]

Ok Nabeel.


In my environment, I intend to have MediaProxy and all clients supporting ICE.

However, in my environment/network doesn't exist a STUN server.


So, my last questions (before I start the MediaProxy installation procedures) about this subject are:


1 -  Does MediaProxy work as a STUN server, or just as a TURN server?


2 - Is it always necessary to provide a STUN server separately, even using the MediaProxy, if direct media is desired?


3 - Let's suppose I will not provide a separately STUN server, in this case will the media always pass through the media relay,?


Thank you again!

Best regards.

Yes, that is how it should work.  ICE tries to connect directly first before trying other methods.  If direct connection fails, then it tries STUN, then media relay.  The clients have to support ICE too.

Hi Nabeel.


Thank you very much for your answer.

If I understood it well, while using MediaProxy, the clients may connect directly, but they may not too. ICE will decide it for me and I don't need to worry about it.

Tell me if I got it, please.


Best regards.

Rodrigo,

It is the responsibility of ICE to determine in which situation it is best to establish a direct connection, versus use of STUN, versus use of a media relay.

We cannot manually decide which clients will connect directly and which will not.

Hi.


In my project, UACs should run direct media. RTP packets direct transmitted from each other.

However, due to NAT presence, I'm thinking about to use MediaProxy.


In this case, is it possible to get direct media after some UAC negotiations passing through the Media_Relay component, or is it impossible? That is, does the media will always pass through the Media_Relay host too?


Any hint will be very helpful!

Thanks alot.
