    Abstract: A system, method, and apparatus are provided to deliver integrated call screen list based telephony services for a subscriber having both landline and mobile wireless telephone terminals. Call screen list based services are selectively provided to a landline or mobile wireless telephone terminal for which an incoming call is being received. These services can be coordinated and integrated between the landline and mobile wireless telephone terminals in various telephony topologies. For example, services can be integrated when the landline and mobile wireless telephone terminals are operably connected to separate mobile and landline telecommunications switching infrastructures or to a common integrated landline and wireless telecommunications switch.
