Abstract:
1. An apparatus, comprising: a network interface having a signature resistance; a telephone circuit coupled with the network interface; power save logic coupled with the telephone circuit and with the network interface; and a non-volatile memory coupled with the power save logic; wherein the power save logic is configured to switch the telephone circuit between an active state and a power save state; wherein the power save logic is further configured to selectively send a signal to an associated network switch coupled with the network interface indicating the telephone circuit is switching to the power save state and to store registration information in the non-volatile memory; wherein the power save logic is configured to selectively change the signature resistance of the network interface to indicate to the associated network switch coupled with the network interface that the apparatus is switching from the active state to the power save state; and wherein the power save logic is configured to selectively directly maintain an active network connection with an associated call control service for the apparatus when the apparatus is in the power save state and in an absence of the associated network switch acting as a proxy for maintaining the active network connection on behalf of the power save logic.
