A traditional way to call for a servant used to be a bell, sometimes on a cord by the master’s chair. Manual doorbells and speaking tubes were common in houses of the 1900’s – actually an acoustic tube extending from the front door to some location from which the homeowner could shout back and forth to visitors - the early intercom.
