摘要： A communications device, connectable to a digital network, such as an ISDN, for setting up a voice call to a remote telephone via the network, the device comprising logic for sending a call signal to the network to establish a call via the network to a local telephone, characterized by call transfer logic for sending further signals to the network to transfer the established call to the remote telephone in response to a confirmation signal from the network indicating that the local telephone has been answered, thereby establishing a voice call between the local telephone and the remote telephone. In one embodiment the device is in the form of a communications adapter for a personal computer.
