ABSTRACT:
a telecommunications carrier other than the carrier of last contact is arranged to a) recognize that the telephone to which a particular call is placed is a disconnected telephone and b) provide different call treatment for the call, e.g., different call handling or different call features or services, as compared to the treatment the telecommunications carrier provides for the same call to the same telephone when it is recognized that the telephone is not disconnected. Advantageously, no effort is wasted in an attempt to complete the telephone call to a disconnected telephone. Such different treatments include 1) simply making no attempt to route the call to the disconnected telephone via the network of last contact, 2) routing the call to a secondary, alternate telephone, and 3) initiating transmission of a page to a pager that is associated with the owner of the disconnected telephone.
