Abstract

An approach is provided for securely and remotely deploying and configuring IP telephony devices. A user applies for IP telephony service. The user is approved and a directory number is assigned to the user'"'"'s IP telephony device. The IP telephony device is connected to a router and powered up. The router detects IP traffic from the IP telephony device and obtains data that uniquely identifies the IP telephony device, such as a Media Access Control (MAC) address. The IP telephony device registers with a certificate authority and receives a digital certificate. The router generates and sends a configuration request to a configuration agent over a secure communications link. The configuration request is verified, a configuration manager is auto-configured if the request is granted and configuration data is provided to the IP telephony device over the secure communications link and implemented by the IP telephony device.
