Abstract: A user accesses a destination such as a call center. The call center generates a record for insertion into the user's personal address book, with a telephone number of the center and metadata concerning a transaction. To place a later call on the same matter, the user selects, either using his telephone or via a separate terminal, the address book entry and the call is made. The center receives the user's telephone number via the calling line identity (CLI) and translates this into a data address so that it can “pull” the metadata from the personal address book. Alternatively the server can translate the center's telephone number into a data address to “push” the metadata to the center.

Abstract: A communication system (1) in which a user (A) can elect to leave a message directly in the mailbox (11a) of another user (B) without calling or disturbing user (B). A store (database 7) is generated and maintained which identifies those users who are allowed direct access to the mailbox of user (B). The store is automatically updated whenever user (B) sends a communication to other users.

Abstract: A user accesses a destination such as a call centre 6; the call centre generates a record for insertion into the user's personal address book (e.g. at server 3) with a telephone number of the centre 6 and metadata concerning a transaction. To place a later call on the same matter, the user selects, either using his telephone or via a separate terminal, the address book entry and the call is made. The centre 6 receives the user's telephone number via the calling line identity (CLI) and translates this (at 8) into a data address whereby it can “pull” the metadata from the personal address book at 3. Alternatively the server 3 can translate the centre's telephone number into a data address to “push” the metadata to the centre.
