This data sheet provides an overview of features and ordering information for Cisco® Unified PhoneProxy, a gateway appliance that provides for secure access to Cisco Unified CallManager from remotely deployed Cisco IP phones and Cisco IP Communicator.
® Unified Communications family of voice, video, and IP communications products and applications helps enable organizations to communicate more effectively-helping them streamline business processes, reach the right resource the first time, and reduce costs and maximize revenue. The Cisco Unified Communications system is an integral part of a complete, integrated business communications solution for organizations of all sizes that also includes network infrastructure, security, and network management products; wireless connectivity; a lifecycle services approach; and flexible deployment and outsourced management options, end-user and partner financing packages, and third-party communications applications.
Cisco Unified PhoneProxy solves critical challenges related to mobility, security, and access management for companies that have adopted the Cisco IP Communications platform.
The need for mobility and the trend toward telecommuting have increased demand for deployment of IP phones to employees' homes and other remote locations. Organizations interested in placing Cisco IP phones in these remote locations have traditionally found it necessary to purchase, configure, deploy, and support a VPN router with the IP phone in each remote location in order to meet security requirements. In some cases this is the best option. In other cases, the cost and complexity of deploying VPN routers to these remote locations can be prohibitive. When VPN routers are not a good option, organizations can use Cisco Unified PhoneProxy to enable secure deployment of Cisco IP phones to these locations without the need for VPN routers.
In addition to securing IP phones deployed to remote locations, Cisco Unified PhoneProxy can also help organizations meet security requirements related to the use of Cisco IP Communicator. When company employees use Cisco IP Communicator from the office, home, or on the road, voice traffic is placed onto the corporate data VLAN and must cross over to the voice VLAN to reach Cisco Unified CallManager, creating a significant security threat because holes must be opened in the firewall between the two VLANs for each computer running Cisco IP Communicator.
Cisco Unified PhoneProxy can be placed in a location of the customer's choice to aggregate voice traffic from all Cisco IP Communicator sessions and send this traffic through to Cisco Unified CallManager, enabling security personnel to open either no holes or just a single hole in the firewall between the data and voice VLANs and monitor and secure this point of entry closely. It also obscures Cisco Unified CallManager information to further protect it from security threats.
KEY FEATURES AND BENEFITS
Application Layer Gateway
Cisco Unified PhoneProxy acts as an application layer gateway, transparently proxying all Skinny Client Control Protocol (SCCP), Real-Time Transport Protocol (RTP), HTTP, and Trivial File Transfer Protocol (TFTP) communications between Cisco IP phones or Cisco IP Communicator and Cisco Unified CallManager, while simultaneously obscuring Cisco Unified CallManager information from these endpoints.
Secure Protocol Support
Cisco Unified PhoneProxy offers full support for secure SCCP and secure RTP to protect conversations from unauthorized interception and eavesdropping. The security features in this appliance do not require the Cisco Unified CallManager cluster to be configured for security.
Cisco Unified PhoneProxy provides a built-in Web application for authentication of users who are activating IP phones for secure use. It also offers a Web Services interface for organizations that prefer to integrate with existing user-authentication services.
IP Phone Activation
Cisco Unified PhoneProxy allows connections to be made to the appliance only by IP phones that have been activated by an authenticated and approved user.
The Cisco Unified PhoneProxy appliance uses a security-hardened operating system and firewall to further enhance network security.
