Abstract:
1. A method, comprising: communicating a first packet to a network element, from a call agent, in order to indicate whether an endpoint can have its power managed by network communications, wherein the first packet includes an Internet protocol (IP) address associated with the endpoint; receiving, at the call agent, a second packet from the network element to identify whether the endpoint can have its power managed, wherein the endpoint is configured to have its power managed via a Power over Ethernet port associated with the endpoint, and wherein a current state of the endpoint is communicated using a Type Length Value (TLV) format; communicating a request from the network element to power off the endpoint, wherein the end point determines whether it can be power off based, at least partially, on the current state of the endpoint; and receiving, from the endpoint, a power off request at the call agent when the end point determines it can be powered off, wherein the call agent can override the power off request.
