Chalk Talk – An Insight to Cisco VPN Phone

So, this is my second chalk talk in two consecutive months (year end happy)!

This chalk talk featured on Cisco Support Community and Cisco Technical Services Newsletter focuses on Cisco VPN phone feature for small business to enterprises looking for a scalable and secure way to let the remote workers/telecommuters connect and leverage the corporate voice resources.

Here’s an excerpt from the article.


In today’s world, organizations are striving to stay connected with their employees. With businesses going 24X7, no organization can afford to have employees disconnected from the enterprise network and not able to access corporate voice or data resources. Understanding that modern day organizations need secure connectivity for their remote employees as well as telecommuters, Cisco has come out with the concept of VPN client on physical Cisco Unified IP Phone. Yes, you read it right, it’s an SSL client installed on a Cisco IP Phone that enables remote workforce and on-the-go employees to get access to corporate UC resources.

Cisco VPN Phone Overview

This new feature is called Cisco VPN Phone, and it leverages Cisco AnyConnect SSL client built into an IP phone’s firmware to connect to enterprise edge firewall (Cisco ASA). Cisco VPN Phone feature has numerous benefits,such as:

  • No additional hardware is required by the end-user except for the IP Phone itself.
  • Cisco Unified IP Phone with Cisco VPN client can get online from wherever Internet access is available.
  • Cisco VPN Phone feature is supported with both Cisco ASA and Cisco IOS routers.
  • Cisco VPN Phone can secure voice and video media along with IP Phone service traffic. This gives additional flexibility to go from a voice-only call to a video call. VPN tunnel applies only to voice, video, and IP phone services. The PC connected to PC port is responsible for authenticating and establishing its own tunnel with VPN client software (Split Tunneling)
  • All settings are configured via CUCM administration, thereby providing ease of administration.
