Chapter 2: VPN overview
Introduction
Setting up a virtual private network provides enterprise telephony services for remote or small office
home office (SOHO) locations through a secure VPN connection to the user’s Enterprise
Communication Manager infrastructure. A VPN uses a high-speed connection to the Internet and
then to the VPN-administered solution in the enterprise network. VPNs provide a significant
improvement of the communications capabilities of SOHO users.
