Abstract
Systems and methods providing integrated voice and data services utilizing wired cordless access with unlicensed/unregulated connectivity sources and wireless access with licensed/regulated connectivity sources. A single telephone directory number is assigned for use with both a mobile wireless telephone and for use with a cordless wired Internet Protocol (IP) telephone. The mobile wireless telephone operates via a conventional licensed spectrum wireless network, and the IP telephone operates over voice over Internet protocol (VoIP) over a broadband packet data network service. Incoming calls simultaneously ring the user's mobile wireless telephone and IP telephone. The user may be provided a personal voice mailbox that may be accessed from their mobile wireless telephone or from their IP telephone. The user may be provided a single services bill associated with use of both telephones.
