Abstract
A telecommunications system provides “feature forwarding” between a fixed telephone unit (such as a desktop wired telephone) and a portable telephone unit (such as a cellular telephone) that are assigned to the same prime telephone number. Thus, only one of the two phones in the telephone pair is accessible (e.g., is forwarded ring signals) at any one time. In one embodiment, the system monitors changes in state regarding whether or not the wireless telephone is in a power recharging state. When the wireless telephone is connected to a power recharger, the wired telephone is designated as the current exclusive telephone to which service features are to be applied. On the other hand, when the wireless telephone is removed from the power recharging state, the common user information necessary for seamlessly implementing common features is reallocated to providing service to the wireless telephone. The common features may include a last number redial feature, a saved number redial feature, and/or features related to accessing voice mail messages.
