We shouldn't use the native bind, if for no other reason on this one than consistency (as well as some other benefits).
I would rewrite these to being something like:
```
instance._webRtcManager.init(
    {
        disableInRinging: A.bind('disableOutRinging', instance),
        disableOutRinging: A.bind('disableOutRinging', instance),
        ...
    }
);
```
