Abstract

System for using a manufacturer issued certificate to authenticate a CTA device during registration with an IP telephony network. In response to providing the manufacturer issued certificate, the issuance of another certificate allows the CTA to be provisioned by a specific IP telephony network. The system includes a method of operating a cable telephony adapter in an IP telephony network. The method includes steps of storing a manufacturer issued certificate in the cable telephony adapter, providing the manufacturer issued certificate to the telephony network, receiving a network issued certificate, and registering for telephony services with the telephony network using the network issued certificate.
