Abstract
An analog telephone adapter (ATA) comprises a dial tone generator, control logic and a packet generator. The dial tone generator generates a dial tone when the ATA is in an unregistered state. The control logic processes a dial-out request when the ATA is in the unregistered state. The control logic directs the packet generator to generate an invite packet for an emergency proxy to handle the dial-out request on behalf of the ATA when the ATA is in the unregistered state.
