An improved call waiting arrangement where a caller is free to exercise discretion in interrupting ongoing telephone calls because the caller is prompted, for example via an audible announcement, that the called party is busy on another call but that the caller may request interruption of the call by remaining off-hook. If the caller believes that his call is sufficiently important, he requests call interruption by remaining off-hook. If the caller chooses not to interrupt, he may make subsequent call attempts promptly because he knows that the called party is busy on another call rather than being away from home. Alternatively, the caller may activate auto-callback such that a call is completed between the two parties as soon as the status of the called station returns to on-hook.
