Abstract
A telephone system employs a novel message system for calling parties. The switch controller includes selectable and programmable announcement machines, while the telephone devices include indicators which allow call transferees the ability to determine the reason the call was transferred, e.g., the called telephone was busy, did not answer or the called telephone party is in conference. When desired, a telephone party is capable of programming the switch controller to reply to any particular incoming phone calls with one of a number of customized or preselected messages.
