An office switchboard is a phone system feature that lets receptionists connect live callers to employees. Many offices in the United States dedicate one person to handling incoming calls from the main phone number. A telephone switchboard is connected to the company's Private Branch Exchange (PBX), so a receptionist can connect calls instantly. Many job descriptions need that certain roles are able to conduct switchboard operations. Modern-day switchboards don't mandate technical knowledge but do need communication skills.
