Abstract:
The Internet Protocol telephony system comprises a registration unit; a signal handling interface; a rules engine; and a call processing interface. The registration unit is configured to store, in association with a customer record, a notification list of one or more telephony devices that that are to be notified upon receipt by the Internet Protocol telephony system of a communication addressed to a customer identifier corresponding to the customer record. The signal handling interface is configured to receive a signal originated by a telephony device. The rules engine is configured to consult the notification list and apply rules logic to determine in what order the one or more telephony devices on the notification list are to be notified. The call processing interface is configured to route notifications to the one or more telephony devices.
