A method of automatically sharing and transferring information between a Work at Work (WAW) ISDN telephone and a Work at Home (WAH) ISDN telephone. This information includes, calling line identifier delivery from the WAW telephone to the WAH telephone, facilitating subsequent transferring of the call to the WAH telephone if desired. Message waiting status is also shared, facilitating the coordination of message waiting lamps at both the WAW and WAH telephone. Information from one telephone to the other is carried transparently through the ISDN network as user-to-user information, calling party subaddress, D channel X.25 packet message, lower layer compatibility or a combination of these elements. The telephones automatically establish ISDN calls between themselves and swap information pertaining to the status of the companion telephones.

Method of sharing and transferring information between ISDN telephones

An intelligent network for providing access to an information network () has a number of central office switches (). Each central office switch () is capable of receiving a call to a centrex telephone number and transmitting a query. A service control point () is coupled to the central office switches () by a SS7 signal link (). The service control point receives the query and transmits a response to the central office switch (). A hub switch () is coupled to the central office switches () and receives the call. The hub switch () contains a digital trunk service () that combines the call with a number of other calls to form a data stream. The data stream is then transmitted to an information network node ().

An intelligent network for providing access to an information network (80) has a number of central office switches (64, 82). Each central office switch (64, 82) is capable of receiving a call to a centrex telephone number and transmitting a query. A service control point (70) is coupled to the central office switches (64, 82) by a SS7 signal link (66). The service control point receives the query and transmits a response to the central office switch (64, 82). A hub switch (75) is coupled to the central office switches (64, 82) and receives the call. The hub switch (75) contains a digital trunk service (76) that combines the call with a number of other calls to form a data stream. The data stream is then transmitted to an information network node (80).
