British multinational telecommunications company BT is terminating its telephone network and shifting all customers over to IP telephony (internet-based voice calls via fiber) by 2025. Broadband, rather than voice, will constitute the primary service.



Other communications companies in Germany, Japan, Sweden, are already in the process of moving voice to run over IP. Orange has set a goal of having all IP (digital) networks by 2020, and Deutsche Telekom aims to migrate all its lines in Europe to digital by the end of 2018.
