You've misunderstood few things there:
- make_call() is not blocking call; it completes immediately and you'll get
the notification in CallCallback
- so there's no need to create a thread to make call
- and you can't get the call's media until CallCallback.on_media_state() is
called and media state is pj.MediaState.ACTIVE
