Abstract: The multi-color light lamp has a base divided into a plurality of segments. The three segments are spaced at 120 degrees. More or less segments can be used. An LED is positioned in each segment, the LED in each segment emits a color distinct from the light emitted by the LEDs in the other segments. If the lamp is to be used for automotive purposes, the LED in a first segment emits red light as a taillight and a stop light, the LED in a second segment emits yellow light a turn signal lamp, and the LED in the third segment emits white light as a backup light. A light pipe is operatively associated with the LEDs in each segment for directing emitted light away from the base. The LEDs (preferably two per segment) are mounted upon a thermally efficient printed circuit board such as a flex-on aluminum board.

Abstract: The present disclosure provides methods of establishing communication between endpoints located in different gatekeeper zones. An electronic message comprising (i) an alias for a first endpoint and (ii) an address of a first gatekeeper associated with the first endpoint is delivered from a first computer associated with the first endpoint to a second computer associated with a second endpoint. Alternatively, the deliverance of the message can occur within the same computer. Upon receiving the message, a second endpoint is instructed to replace its original gatekeeper address with the gatekeeper address listed in the message. Subsequently, the second endpoint uses the alias of the first endpoint to establish communication with the first endpoint.
