Abstract: A calendar system within a telephone system includes an interface for obtaining information from a calling party, calendar data which includes a calendar for a called party, and an agent. The agent, in response to a request to schedule a telephone call with the called party, searches the calendar of the called party to determine an available slot for the telephone call. After confirming that the available slot for the telephone call is acceptable to the calling party, the agent schedules the telephone call in the available slot of the calendar for the called party.
