wrtc.acceptAudio is a boolean property controlling if we want to receive audio in calls or not. It controls if we should ask other end of calls to send us audio media stream or not. Please note that this is just a request - other end might decide to not send audio even though we asked for it.
wrtc.acceptAudio affects all calls created by the wrtc object.
Boolean controlling audio reception:
true
wrtc.acceptAudio is usually set in wrtc.init(). If you for some reason want to change it later you need to call wrtc.changeMedia() after.
