  • Method for accommodating ported directory numbers affected by call block controls implemented in a telecommunications network
    Patent number: 5896447
    Abstract: A method for implementing all blocking controls in a telecommunications system supporting ported directory numbers comprises initializing each switch with a call blocking control. In the preferred embodiment, ported directory numbers are identified, and a number portability data base is accessed to aid in determining whether the call blocking control applies to the ported directory number. If the ported directory number is not subject to the implemented call blocking control, the ported directory number is exempted.
