Full Description

Update resulting from work on number screening. To define enhancements of the existing CLI supplementary services in the ISDN and PSTN in order to limit the number of situations that calls will be rejected due to Anonymous Call Rejection (ACR) reasons. The purpose of these enhancements are to specify those network facilities that can be used to offer a solution for specific situations (e.g. calls originating from call centres and traffic being diverted due to least cost routing scenarios) where a number can not be presented in spite of the fact that the caller is willing to identify himself/herself. These enhancements should not interfere with the authentication function of the CLI supplementary services. Reference document: ETSs 30089 Ed.1 and 300 090 Ed.1.
