A method on a wireless user equipment (UE) device facilitates integration of an outgoing cellular call as an enterprise call. The UE device attaches to a wide area cellular network on which the device has a non-enterprise address. Upon blocking incoming calls, the UE device sends a request to a node in a data network to initiate an outgoing cellular call with an expectation of receiving an incoming circuit-switched (CS) call back from the network node within a time window. The incoming CS call contains an enterprise address associated with a user of the wireless UE device as a calling line identity to identify that the incoming CS call is related to the request to initiate the outgoing cellular call. The UE device indicates to the network node that a call leg is established between the enterprise user and the network node.
