Patent ID: 8265614

Claim:
A method, operable on a wireless user equipment (UE) device, for facilitating integration of an outgoing cellular call as an enterprise call, wherein said outgoing cellular call is originated by an enterprise user towards a called party when said enterprise user is attached to an external wide area cellular network via a mobile communications device, said enterprise user having an enterprise address and a non-enterprise address, comprising: upon blocking all incoming calls to the UE device, sending a data request to a network node in a data network for initiating said outgoing cellular call to said called party with an expectation to receive an incoming circuit-switched call back from said network node within a time window; if said time window has elapsed without receiving said incoming circuit-switched call from said network node, continuing to send said request a select number of times; else, receiving said incoming circuit-switched call from said network node, said incoming call containing said enterprise address as a calling line identity to identify that said incoming circuit-switched call is related to said request to initiate origination of said outgoing cellular call; and providing an indication to said network node that a call leg is established between said enterprise user and said network node.
