LPS-40873 WebRTCManager: implement call
LPS-40873 Rename
LPS-40873 Move it to where it's used
LPS-40873 I'm not sure which one is clearer, call or connect. But we have the idea of a connection already, so I just kept it as that to remove one more type of thing. But if you think call is better, please rename it back.
