ABSTRACT:
In a telecommunications system that includes a plurality of user terminals and terminal translations that define attributes of the individual terminals, shared use of the terminals by a plurality of users, or use by a user of different ones of the terminals at different times, is facilitated. Each terminal's physical translations, which include for each terminal those attributes that are independent of the users of the terminal and which include a physical extension number, are associated with the corresponding terminals. Each terminal's default terminal translations, which include for each terminal those attributes that are dependent on the users of the terminal and which include a call-coverage path, also are associated with the corresponding terminals. Each user's logical translations, which include for each user those attributes that are independent of the terminals used by the user and which include a logical extension number and a call-coverage path, are associated with the corresponding users. Prior to a user logging on at a terminal, call processing uses the terminal's associated physical and default terminal translations to process calls originating at the terminal or addressed to the terminal, and redirects calls addressed to the user to the call-coverage path specified in the user's logical translations. Subsequent to a user logging on at a terminal, call processing uses the terminal's associated physical translations and the user's associated logical translations to process calls originating at the terminal or addressed to the user, and continues to use the terminal's associated physical and default terminal translations to process calls addressed to the terminal.
