Abstract
Abstract In many business applications, data about a client is created and entered on an agent's data terminal during a teleconference with the client. Often, it is necessary to transfer the client to a specialist during the course of the conversation. This invention describes a method of transferring the call and the data terminal information associated with the call to any available phone extension with an associated data terminal. A plurality of Computerized Branch Exchanges (1) (CBX) are joined via a network means to facilitate the transfer of the call and pass a host program (3) the phone source extension (4) and the destination extension (6) for the transfer. The host program looks up the source and destination extensions in a phone to terminal file and determines the network address of the data terminals (5, 7) involved and transfers the appropriate host application terminal display to invoke a transfer of display information. The host application sends the data terminal information to the destination data terminal display in conjunction with the transferred phone call.
