Abstract: A method is provided for tracking the physical location of IP phones and IP devices in a network. According to the invention, the IP phone or IP device detects its own current location and then informs the PBX controller or the location database to which it is connected. The capability is integrated in every IP phone and IP device. The PBX or location database then takes appropriate action, such as updating the ALI mapping for the phone or location information for the IP device.

Abstract: A disposable rodent trap is formed of an aluminum beverage can comprising an internal chamber, a bottom end wall with an opposite end wall including an entry opening therein of sufficient size to permit a rodent to pass into the internal chamber. A door member in the form of a can end is positioned externally of said end wall and movable into a closed position covering and blocking the entry opening by a rubber band. A latch means normally holds the door open by engagement with an edge surface of the entry opening but is movable by rodent contact inside the chamber to unlatched position to permit the rubber band to move the door member to its closed postion to trap the rodent in said internal chamber.
