To establish a WebRTC peer connection open this page in another Browser Tab or Window and set the IDs so that the Local and Remote IDs are opposite. The format of the IDs does not matter they just need to be opposite between the two connecting peers.

For example:

Browser 1 Browser 2
Local ID solo-123 solo-456
Remote ID solo-456 solo-123

If successful the video control in each browser should display white noise.
