Methods, systems, and devices are provided for controlling the power level of voice signal streams. One embodiment of a network device having router functionality includes a processor, memory in communication with the processor, and program instructions. The program instructions can be stored in memory and executable on the processor to designate a fail-over virtual router interface for a first physical router on a second physical router based on addressing information obtained via communication between the first physical router and the second physical router.
