WebRTC ~ Possible to connect when knowing IP and PORT without using Intermediate Servers

Question

I know there is lot's of documentation about WebRTC out there so I am sorry if I missed it:

My question is the following:

Is it possible to connect from client to client without using an intermediate server. ( Including an intermediate server to set up the connection )

Take as example two clients that know each other IP addresses and the ports they are using for RTC. Both did they already downloaded the webpage. Is it possible for them to connect without an intermediate signal server?

I hope you would point me to a good source of how this is possible! Or why not!

Thanks

Answer 1

It is not as easy as that to set up the connection. There is more information that needs to be provided than ip and port. There are 'offer', 'answer' and 'candidates' that are sent between the peers.

These are readable text and the could very well be typed in by the user but since they are quite large, it is more easy to provide them via the server in the middle.

You could mail them and type them in at the remote peer...
