Abstract
A method for using femtocell as a telephone exchange is provided. The method comprises the following steps. A femtocell registers to a core network via an Internet. The femtocell receives a phone call, and determines whether the phone call comes from the core network or the internal network. If the phone call comes from the core network, then the femtocell automatically answers the call and provides a prompt. The femtocell determines whether an input number of the phone call is an internal extension number. If the input number is the internal extension number, then the femtocell transfers the phone call to a corresponding internal extension.
