In one aspect of the invention, a method for call forwarding synchronization includes allowing a telephone subsystem to forward calls for a telephonic device to a first call forwarding destination. The method also includes allowing a wireless subsystem to forward calls for a mobile station to a second call forwarding destination. The mobile station is associated with the telephonic device. The method further includes determining a registration state of the mobile station. In addition, the method includes synchronizing the call forwarding destinations for the mobile station and the telephonic device in response to a change to at least one of the registration state, the first call forwarding destination, and the second call forwarding destination.
