docs: Returns the other side of a local channel. <br>
  Local channels consist of two sides, like "Local/1234@from-local-60b5,1"
  and "Local/1234@from-local-60b5,2" (for Asterisk 1.4) or
  "Local/1234@from-local-60b5;1" and "Local/1234@from-local-60b5;2" (for
  Asterisk 1.6) this method returns the other side.
  
  @param localChannel one side
  @return the other side, or <code>null</code> if not available or if the
  given channel is not a local channel.
