After answering a call (successfully), the peers are not connected

[s1lviu]

Hi, @muka
Thank you for the efforts of doing this project.
I'm working on a simple open source project. I'm a total newbie in go, but I managed to do an audio call from a webpage where I implemented the PeerJS client.

The issue is that even the call appears as answered in go, the peers are not connected. Do I miss something?

Thanks!

	// Create a new peer with these options
	myPeer, err := peer.NewPeer("f81b8d75-3ee0-4a22-ab46-eea667aeb499", options)

	defer myPeer.Close()

	myPeer.On("call", func(raw interface{}) {

		call, ok := raw.(*peer.MediaConnection)
