Mobile phone call openings: tailoring answers to personalized summonses

Conversation analytical (CA) methodology was used to specify 10 the new opening practices in Finnish mobile call openings, which differ systematically from Finnish landline call openings. Since the responses to a mobile call orient to the summons identifying the caller, answers have changed and diversified. A known caller is greeted. The self-identification opening that was canonical in Finnish landline calls is mainly used for answering unknown callers, while channel-opener openings involve orientation to ongoing mutual business between the speakers. Some of these changes reflect real-time coordination of the social action that the mobility of mobile phones enables. In all, the adoption of new ways of answering a call shows that people orient themselves to affordances that new technologies allow them. Mobile phone communication opens a salient new area both for the analysis of talk-in-interaction itself and also for understanding communicative behaviour in the era of ubiquitous information technology.
