See Restriction filters on page 104 and theProgramming chapter of the Modular ICS 7.1 SystemCoordinator Guide for more information.Tips - You can also use routing as an alternative methodfor a direct-dial number. For example, create a destinationcode 0 and program the number of the internal or externaldestination as the DialOut.
