We examine the activity of securing the attention of a prospective interlocutor by means of a summons-answer sequence when the summoned party is walking away from the summoner. We focus on two forms of first-name summonses. Calling-out summonses are produced when the coparticipants are at a significant distance from each other and the summoner remains stationary. Halting summonses are produced when the summoner is moving towards the summoned party and is about to reach them. The data are video recordings of hospital staff corridor interactions oriented towards recruiting a coworker for a practical task.
