The paper is based on a study on the uses of the telephone in 317 French homes. Detailed billing data over four months were collected and compared with interviews concerning each regular phone user in the household. We focus here on the correlation between the observed duration of phone calls and the gender of callers and receivers. The reasons why women telephone more are discussed and related to the gender homophily in telephone networks. Data also show that the duration of phone calls depends on the receiver's gender. We suggest that politeness rules may govern the telephone call, did we argue that these civility rules explain in part why the receiver's gender exerts the greatest effect on how the call is managed and on its overall duration. We propose to explore the hypothesis that telephone calls have an interactional format similar to that of a visit, but that status differences between caller and receiver may influence the unfolding of interactions between men and women through the caller's adjustment of his or her interaction style to the receiver's gender.
