Abstract

A telecommunication protocol message that allows redirection of a call received by a first telephone station set to a second telephone station set or other terminal equipment by the first telephone station set transmitting the redirect message to a telecommunication system connected to the first telephone station set. The redirect message includes the identification of the user of the first telephone station set as well as the telephone number of the second telephone station set or terminal equipment. The telecommunication switching system is responsive to the redirect message to reroute a call to the second telephone set. The redirect message allows the first station set to transmit only one message to the telecommunication switching system to accomplish the functions of rerouting the call. In addition, the redirect message gives a BRI (basic rate interface) station set the capability of automatically forwarding certain types of calls. Since a call setup message includes the telephone number of the originating station set, the BRI station set can be programmed to transfer calls to different station sets based on the originating station number. In addition, with the proliferation of facsimile machines (often referred to as FAXs), there is a problem in coordinating an individual's telephone number with the individual's FAX number by a person wishing to send a FAX. Using the redirect message, the BRI station set can be programmed to examine the bearer capability information encoded as an Information Element, IE, in the setup message to determine the type of call that is being set up. If a digital data call is being set up, the BRI station set then examines the higher layer capability IE in the setup message to determine whether or not it is a FAX message. If it is a FAX message, the BRI station set will automatically forward the call to the FAX designated by the user of the BRI station set. Further, the station set will display a message indicating that a FAX message had been forwarded. Using this technique it is only necessary to know a person's telephone number in order to send a FAX to that person.
