• i) said telephone number disposition calendars contain information relating to one or more of a plurality of caller response options, each of which is individually selectable according to respective preselected access times and dates assigned to each of said telephone numbers;
• b) line voltage monitoring means for monitoring line voltage on an analog telephone line connected to said system, said voltage monitoring means including:
• i) means for detecting when a threshold line voltage is exceeded in order to determine whether said analog telephone line is in an on-hook state or an off-hook state;
• ii) means for detecting a particular voltage fluctuation when said analog telephone line is in said on-hook state, said particular voltage fluctuation corresponding to a ring signal associated with an incoming telephone call
• c) means for identifying the telephone number of said incoming call during said on-hook state of said analog telephone line;
• d) means for requesting and detecting a code associated with said incoming call during an off-hook state of said analog telephone line:
• e) system control means including a clock operative to assign a time and date stamp for each incoming call, compare at least one of the number and code of detected incoming calls to the telephone numbers and to disposition calendar information stored in said database, and execute an appropriate caller response option according to preselected disposition calendar information assigned to each telephone number;
