Configuring Virtual Private Networks
The Cisco VPN Client for Cisco Unified IP Phones adds another option for customers attempting to
solve the remote telecommuter problem by complementing other Cisco remote telecommuting offerings.
• Easy to Deploy—All settings configured via CUCM administration.
• Easy to Use—After configuring the phone within the Enterprise, the user can take it home and plug
it into their broadband router for instant connectivity, without any difficult menus to configure.
• Easy to Manage—Phone can receive firmware updates and configuration changes remotely.
• Secure—VPN tunnel only applies to voice and Cisco Unified IP Phone services. A PC connected to
the PC port is responsible for authenticating and establishing it own tunnel with VPN client
software.
