1. A method, comprising:
by a femtocell gateway of a carrier network, receiving a handoff operation for a call between a first communication device in an enterprise network and a second communication device, wherein the handoff operation is received from a femtocell access point of the enterprise network;
by the femtocell gateway, receiving a routing number from the carrier network in response to a request from the femtocell access point; and
by the femtocell gateway, rerouting the call from being between an enterprise gateway server of the enterprise network and the femtocell access point to being between the enterprise gateway server and a destination gateway of the carrier network using the routing number.
