History
Describes the Call Intrusion supplementary service (SS-CI), which is applicable to basic services supported by Private Telecommunication Networks (PTNs). Basic services are specified in ETS 300 171. This is a supplementary service which enables the user to establish communication with a busy called user (user B) by breaking into an established call between user B and a third user (user C).
