1. A method comprising:
- receiving a first message at a switching device of a network including a packet-switched computer network, the first message received according to a node-to-node protocol for communication across only a single network link, the first message indicating a change of an endpoint communication device of the network from a first configuration for local operation of the endpoint communication device on behalf of a first telephone service account to a second configuration for local operation of the endpoint communication device on behalf of a second telephone service account, the local operation on behalf of the second telephone service account for communicating telephony information over the packet-switched computer network; and
in response to receiving the first message,the switching device determining from information in the first message an account identifier specifying the second telephone service account, andsending from the switching device a second message including the determined account identifier, the second message sent in support of a location service.

Abstract
Techniques for providing location information describing a communication device configured to exchange telephony information over a computer network. A switching device of the computer network receives a first message according to a node-to-node communication protocol, the first message indicating that the endpoint communication device includes a configuration for a mode of operation on behalf of a telephone service account. The switching device determines from the first message an identifier of the telephone service account and sends the determined identifier in a second message via the computer network, the second message in support of a location service.

9. A switching device comprising:
-
a port to receive a first message from a network including a packet-switched computer network, the first message received according to a node-to-node protocol, wherein the first message is interpreted as being communicated across only a single network link, the first message indicating a change of an endpoint communication device of the network from a first configuration for local operation of the endpoint communication device on behalf of a first telephone service account to a second configuration for local operation of the endpoint communication device on behalf of a second telephone service account, the local operation on behalf of the second telephone service account for communicating telephony information over the packet-switched computer network; a link layer processor including circuitry responsive to the first message to determine from information in the first message an account identifier specifying the second telephone service account; and a network interface responsive to the first message to send from the switching device a second message including the determined account identifier, the second message sent in support of a location service. - View Dependent Claims (10, 11, 12, 13, 14)

15. A machine-readable storage medium having stored thereon instructions which when executed cause a machine to perform a method comprising:
-
receiving a first message at a switching device of a network including a packet-switched computer network, the first message received according to a node-to-node protocol, the first message indicating a change of an endpoint communication device of the network from a first configuration for local operation of the endpoint communication device on behalf of a first telephone service account to a second configuration for local operation of the endpoint communication device on behalf of a second telephone service account, the local operation on behalf of the second telephone service account for communicating telephony information over the packet-switched computer network; and in response to receiving the first message, the switching device determining from information in the first message an account identifier specifying the second telephone service account, and sending from the switching device a second message including the determined account identifier, the second message sent in support of a location service. - View Dependent Claims (16, 17, 18, 19, 20)

21. A network device comprising:
-
a memory to store an account identifier specifying a telephone service account associated with an endpoint device of a network; a link layer controller coupled to the memory, the link layer controller including circuitry to access the account identifier and to generate a message based on the accessed account identifier, the message indicating a change of an endpoint communication device from a first configuration for local operation of the endpoint communication device on behalf of a first telephone service account to a second configuration for local operation of the endpoint communication device on behalf of a second telephone service account, the local operation on behalf of the second telephone service account for communicating telephony information over the packet-switched computer network; and a network interface coupled to the link layer controller, the network interface to send the message to a switching device of the network, including sending the message according to a node-to-node protocol for communication across only a single network link. - View Dependent Claims (22)
