Abstract
A method and apparatus for providing security to an endpoint device are disclosed. For example, the method receives a signaling message by the endpoint device. The method processes the signaling message, if the signaling message is received from a device associated with one of one or more Internet Protocol (IP) addresses in an Access Control List (ACL), and discards the signaling message, if the signaling message is received from a device not associated with one of the one or more IP addresses in the ACL.
Claims20
A method for processing a signaling message at an endpoint device, comprising:
- receiving the signaling message by the endpoint device, wherein the endpoint device comprises an internet protocol phone;
- processing the signaling message by the endpoint device, when the signaling message is received from a network element associated with one of a group of Internet protocol addresses in an access control list, wherein the network element is a component of a telecommunication service provider network and wherein the signaling message comprises a call setup signaling message for a call to the endpoint device from an another endpoint device;
- and
- discarding the signaling message by the endpoint device, when the signaling message is received from a device not associated with one of the group of internet protocol addresses in the access control list.
A non-transitory computer-readable medium storing a plurality of instructions which, when executed by a processor of an endpoint device, cause the processor to perform operations for processing a signaling message at the endpoint device, the operations comprising:
- receiving the signaling message, wherein the endpoint device comprises an internet protocol phone;
- processing the signaling message, when the signaling message is received from a network element associated with one of a group of internet protocol addresses in an access control list, wherein the network element is a component of a telecommunication service provider network and wherein the signaling message comprises a call setup signaling message for a call to the endpoint device from an another endpoint device;
- and
- discarding the signaling message, when the signaling message is received from a device not associated with one of the group of internet protocol addresses in the access control list.
An apparatus for processing a signaling message, comprising:
- a hardware processor of an endpoint device comprising an internet protocol phone;
- and
- a computer-readable medium storing instructions which, when executed by the processor, cause the processor to perform operations, the operations comprising:
- receiving the signaling message;
- processing the signaling message, when the signaling message is received from a network element associated with one of a group of internet protocol addresses in an access control list, wherein the network element is a component of a telecommunication service provider network and wherein the signaling message comprises a call setup signaling message for a call to the endpoint device from an another endpoint device;
- and
- discarding the signaling message, when the signaling message is received from a device not associated with one of the group of internet protocol addresses in the access control list.
