Abstract
Relates to arrangements for utilizing an originating caller's customer network identifier (ONI) to provide special treatment of a call, especially one that terminates outside the caller's network. The ONI is recognized in an originating switching system and is transmitted in an initial address message (IAM) to the terminating switching system for serving the call. In the terminating switching system, the ONI is used to screen the call for special treatment such as denied termination, denied termination for collect calls, or direct completion to a principal of a principal-secretary group. The ONI is also used for screening for use of originating services for members of a network. The originating or terminating switch can also query a data base to obtain screening data.
