Continuing a call on a call appearance that has been excluded from the call
Abstract:
A method and apparatus are disclosed that enable a user who is on a call using a call appearance at a first terminal to continue the call on a call appearance at a second terminal, wherein the second terminal has been excluded from the call. In the illustrative embodiment of the present invention, a private branch exchange that handles both telecommunications terminals receives a first signal that indicates that the first terminal has disconnected from the call. The private branch exchange then receives a second signal that indicates that the second terminal has gone off-hook or otherwise indicates a request to be added to the call. If the private branch exchange has received the second signal within a predetermined time interval after having received the first signal, then it adds the second terminal to the call.
