In one embodiment, a network node is operable, responsive to receiving a request from an enterprise user to initiate origination of an outgoing cellular call to a called party, for establishing a first call leg to the enterprise user by sending a circuit-switched call that identifies an enterprise address of the enterprise user as a calling line identity. The network node includes functionality for establishing a second call leg to the called party upon receiving an indication from the enterprise user that the first call leg has been established. The first and second call legs are then patched to establish an end-to-end communications path between the enterprise user and the called party, wherein the enterprise address instead of the non-enterprise address is presented to the called party as a calling line identity with respect to the outgoing cellular call from the enterprise user.

1. 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; andproviding an indication to said network node that a call leg is established between said enterprise user and said network node. 2. The method as recited in claim 1, wherein said data request is sent as a Short Message Service (SMS) message. 3. The method as recited in claim 1, wherein said data request is sent as an Unstructured Supplementary Service Data (USSD)-based message. 4. The method as recited in claim 1, wherein said data request is sent as a Session Initiation Protocol (SIP) message. 5. The method as recited in claim 4, wherein said SIP message comprises a SIP INVITE message. 6. The method as recited in claim 4, wherein said SIP message comprises a SIP REFER message. 7. The method as recited in claim 1, wherein said data request is sent as an Internet Protocol (IP)-based message. 8. The method as recited in claim 1, wherein said data request includes said enterprise address, said non-enterprise address, said called party's address, and a privacy indication. 9. The method as recited in claim 8, wherein said enterprise address comprises one of a SIP Uniform Resource Identifier (URI) and an E-164 number. 10. The method as recited in claim 8, wherein said non-enterprise address comprises a cellular telephony network number in E-164 format. 11. The method as recited in claim 8, wherein said called party's address comprises one of a SIP Uniform Resource Identifier (URI) and an E-164 number. 12. The method as recited in claim 1, wherein said time window is effectuated based on commencing a timer with respect to sending said request. 13. The method as recited in claim 12, wherein said timer is terminated upon receipt of said incoming circuit-switched call from said network node. 14. A user equipment (UE) device operable to generate 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 UE device is attached to an external wide area cellular network, said enterprise user having an enterprise address and a non-enterprise address, comprising: means for sending a data request to a network node in a data network to initiate origination of 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 and for continuing to send said request a select number of times if said time window has elapsed without receiving said incoming circuit-switched call from said network node, said request being sent upon blocking all incoming calls to the UE device; andmeans for 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. 15. The UE device as recited in claim 14, further comprising means for providing an indication to said network node that a call leg is established between said UE device and said network node. 16. The UE device as recited in claim 14, further comprising means for disabling incoming calls to said UE device, said means for disabling being operable upon sending said request.
