Patent ID: 7965701

Claim:
A method for communicating with a telephony enabled device, wherein the device is also capable of communicating on an Internet protocol based (IP) network, comprising: activating the telephony enabled device for communicating on a telephony network and communicating on the IP network; the telephony enabled device broadcasting on the IP network a request for initial IP network information; in response to the broadcast, the telephony enabled device first receiving an IP address for the telephony enabled device via the first communication; in response to the broadcast, the telephony enabled device performing a first set of communications with a network node identified by a first IP address for establishing a first communication therebetween; the telephony enabled device second receiving update information related to an update of operational information used in operating the telephony enabled device, wherein the update information is received via an encrypted and authenticated communication on the IP network from the network node; the telephony enabled device third receiving a second IP address from the network node for an IP server; in response to receiving the second IP address, the telephony enabled device fourth receiving security information for encrypting and authenticating IP communications received by the telephony enabled device from the IP server, wherein the security information is determined via an encrypted and authenticated communication on the IP network; the telephony enabled device authenticating, with the security information, an IP communication between the IP server and the telephony enabled device, including a substep of authenticating whether an IP communication received on a particular port of the telephony enabled device is from the IP server; the telephony enabled device decrypting, with the security information, the IP communication between the IP server and the telephony enabled device; and wherein subsequent processing of each communication C of at least most IP communications on the port is dependent upon a corresponding result for authenticating that the communication C is from the IP server, wherein when said result indicates the communication C is not from the IP server, at least one instruction in the communication C is not processed in a manner that the instruction would be processed if said result indicated C were from the IP server.
