OIP and OIR supplementary services are based on stage one and two of the ISDN CLIP and CLIR supplementary services.
The OIP service provides the terminating user with the possibility of receiving trusted (i.e. network-provided) identity
information in order to identify the originating user.
In addition to the trusted identity information, the identity information from the originating user can include identity
information generated by the originating user and in general transparently transported by the network. In the particular
case where the "no screening
" special arrangement does not apply, the originating network shall verify the content of
this user generated identity information. The terminating network cannot be responsible for the content of this user
generated identity information.
The OIR service is a service offered to the originating user. It restricts presentation of the originating user's identity
information to the terminating user.
When the OIR service is applicable and activated, the originating network provides the destination network with the
indication that the originating user's identity information is not allowed to be presented to the terminating user. In this
case, no originating user's identity information shall be included in the requests sent to the terminating user. The
presentation restriction function shall not influence the forwarding of the originating user's identity information within
the network as part of the supplementary service procedures.
