ABSTRACT:
There is disclosed a method and system for redirecting a telephone call incoming to a first line to a selected one or more second lines. In operation, ringing signals initially applied to the first line by the central switching network are inhibited and instead a three-way calling connection is established to the second telephone. Ringing signals applied to the second telephone from the second network connection are detected and cause ringing signals to be applied to the first telephone substantially concurrently with the application of ringing signals to the second telephone. The system is controlled by a processor located in physical proximity to the first telephone.
