Terminal device, and intercom system provided with terminal device

A terminal device which communicates with room parent devices installed in respective rooms, comprising:

• an input unit which enables input of at least a dweller name as a call manipulation for calling a particular room parent device;
• a storage unit which is stored with a call table in which a room number, a dweller name and room parent device identification information assigned to each of the room parent devices are correlated with each other;
• and
• a control unit which determines a call target room parent device on the basis of an input content of the call manipulation and the call table and performs a call control for calling the determined room parent device, wherein:
• in adding a new dweller name for an existing room number to the call table stored in the storage unit, the control unit automatically associates the room parent device identification information with the new dweller name by registering the new, dweller name with the room parent device identification information without having to register other dweller names associated with the same room parent device identification information.
