A method and apparatus of filtering packet data for an anonymous user device in a packet data network communication system (Fig.3) includes a first step of initiating a call from an anonymous user device on a home network (30). A next step includes assigning an interim identity and interim IP address to the user device (36). A next step includes determining a level of service access of the data packets from the user device (34). A next step includes mapping the level of service access of the user device to the IP address. A next step includes defining permissible routing identities per the level of service access (40). A next step includes routing the data packets of the call along with the associated IP address to only those location addresses from the defining step (42).
