Abstract: The application relates to the registration of the identity of a telephone terminal in association with the identity of a computer terminal in a Computer Technology Integration environment CTI-enabled switching apparatus and a registration server interconnected by a CTI-link and a telephony link. A registration method whereby the registration is essentially achieved by using the telephony link to present PIN data inputted using the telephone terminal to the registration server and to identify the from the CTI-link the identity of the telephone terminal which presents the PIN data over the telephony link faces the problem of how to tie in the correct CLI to the correct call. This problem is solved by the application in that the port of telephony link used by the switching apparatus for the call by which the PIN data is transmitted is transmitted in combination with the CLI over the CTI-link.

Abstract: An integrated communications application reads information copied to a shared buffer by a user from another application. The information copied can comprise any format and can originate from any application from which the user can paste information. In this way there is no restriction on the source of information. The computer application reads the buffer and copies the information so that it can subsequently process it to determine if it conforms to a predetermined data-type. One or more means to communicate with an entity whose address corresponds to the data-type are then determined from a single data-type. This enables the application to revert to an alternative means of communication automatically if the means first used to try to communication with the entity is not successful.

Abstract: In a Computer Telephony Integration environment, to reduce the risk of inadvertent or fraudulent registration of the association of a user's computer terminal with the wrong telephone, i.e. one other than the telephone adjacent to the computer terminal or the user's mobile telephone, a host computer instructs the user via a screen display to call a particular extension of a CTI-enabled communications switching system. When a call to that extension is detected, the communications switching system reports this to the host computer which stores a set of at least one characteristics of the calling telephone terminal including a unique terminal identifier. The user is then provided with a second telephone number via the computer terminal associated with the telephone terminal which was detected as having dialled the first number.
