This IDC Insight is part of a range of documents that IDC's EMEA Telecommunications and Networking team is publishing with regard to enterprise voice connections. The aim of these documents is to map the installed and forecast user base of various types of voice connections to demographic and company data.
This study focuses on the shift from CPE-based and hosted-based voice mode to a public-based one. As with previous related studies, it focuses on the type of voice connections used by each employee and provides insight into the major drivers and patterns of change in the enterprise environment.
This IDC insight was built based on IDC's Call Control Update: The Shift from CPE-to Hosted-Based Voice User Base in Western Europe, 2009–2014 (IDC #CT52T, January 2011). The data held here within this update should be seen and treated as the most up-to-date representation of the number of business voice connections, including previously published historical data.
