====== onEarlyMedia() ======
wrtc.onEarlyMedia() is called when media (sound) is received from a remote client we have called before the actual call begins. Early media is usually used to transmit the ringing sound as media instead of [[ixnx:wrtc:js:api:wrtc:onringing|wrtc.onRinging()]]

When this event occurs you should silence any ringing sounds you might have started playing in [[ixnx:wrtc:js:api:wrtc:onringing|wrtc.onRinging()]]

===== Occurs =====
When early media (sound) is received from a client we have called before [[ixnx:wrtc:js:api:call:is|call.is("connected")]] returns true.

===== Arguments =====
wrtc.onEarlyMedia(call)
  * call - the [[ixnx:wrtc:js:api:call:start|call]] object raising the event
