CALL FORWARDING SYSTEM Abstract The above problem is overcome and a technical advance is achieved in accordance with the present invention which relates to a flexible, call forwarding and rerouting system which can be programmed by a user. In accordance with the principles of the invention, calls cannot only be forwarded from the called telephone to a plurality of telephone, in sequence, but, as the call is forwarded from onetelephone to another, the number of rings at each telephone can be determined by the user. In this manner, the call searches for the called party. In a further embodiment, the system can route a call from a telephone coupled to an on premises switch located at one central office to a telephone coupled to an on premises switch located at another central office. In another embodiment, the system can be programmed to route a call which remains unanswered after having been forwarded to various telephones to an answering machine which can beconnected to either the called telephone or to a different telephone which may have been rung previously. In still another embodiment, priority routing procedures can be established for calls received from specific telephones. For example, in telephone systems such as Intelligent Networks/ Integrated Services Defined Network, (IN/ISDN), where the calling number can be identified by the called telephone before the called telephone is answered, special routing procedures can be established for specific calls.
