Abstract
A network device has at least two communication ports to allow the device to communicate with at least two telephony devices. The device has a ring manager to determine if any of the communication ports are silent ports ready to transition from silent to ringing, determine if there is power available to transition the silent ports to ringing ports, transition silent ports to ringing ports until an amount of available power is depleted, and queue remaining silent ports until power becomes available, such that silent ports in the queue may experience cadence distortion.
