Abstract
A method and apparatus for screening a call in a telecommunications network having a first system comprising a first subscriber station and a second system comprising a second subscriber station, associated with the first subscriber station by a predetermined relationship. Each subscriber station in the first system has a unique subscriber number and the second system having a general number for all subscriber stations. In the method and apparatus, call setup requests for calls to the general number of the second system are screened to determine if the call was originally made to the number of the first subscriber station and then forwarded to the general number of the second system, or if the call was originally made to the general number. If the call was originally made to the first subscriber station, only the second subscriber station is alerted. If the call was originally made to the general number, all the subscriber stations in the second system are alerted.
