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 Computerized Branch Exchange (CBX) is used to transfer the call and pass a host program the phone source extension and the destination extension 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 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.
