The study of dialogue interpreting, particularly over the phone, has been traditionally undertaken under the scope of public service interpreting. However, telephone interpreting nowadays is becoming popular in other settings, such as in the domain of roadside assistance. The aim of this contribution is to present the initial steps of a research project about telephone interpreting and roadside assistance. The methodology, based on corpus and discourse analysis, is described and preliminary findings are offered, which confirm the existence of a common structure for interpreter-mediated conversations between insurance agents and clients.
