12. The method as in claim 1 further comprising:

via a communication management resource selecting the transport protocol, adjusting, for the selected transport protocol, timing of message retransmission from the communication management resource to the user equipment, the adjustment accommodating an outage of communication occurring when handing off the second communication session from the first wireless network to the second wireless network.

13. The method as in claim 1 further comprising:

implementing message retransmission in conjunction with the selected transport protocol, the implemented message retransmission being adaptive based on a message transmitted to the user equipment and a corresponding response message received from the user equipment.

14. The method as in claim 1 further comprising:

initially establishing the second communication session over the first wireless network; and

via a command communicated over a first communication link between the first wireless network and the user equipment, notifying the user equipment to switchover to signaling over the second wireless network to continue establishing the second communication session over a second communication link between the user equipment and the second wireless network.

15. The method as in claim 1 , wherein the notification indicates a type of interworking and corresponding signaling supported between the first wireless network and the second wireless network.

16. The method as in claim 1 , wherein a user of the user equipment provides input to use wireless services provided by the second wireless network, the input indicating the type of signaling supported between the first wireless network and the second wireless network.

17. The method as in claim 16 , wherein the input indicates that the interworking between the first wireless network and the second wireless network operates without N26 signaling.

18. The method as in claim 1 , wherein establishing the second communication session includes:

establishing the second communication session for the phone communication using session signaling over TCP or UDP between a communication management resource and the user equipment.

19. A system comprising:

a communication management resource facilitating wireless communications associated with a first wireless network and a second wireless network, the communication management resource operable to:

receive a notification indicating that user equipment is registered to use a first wireless network and a second wireless network, the notification further indicating a type of signaling supported between the first wireless network and the second wireless network;

in response to detecting a phone communication associated with the user equipment, selecting a transport protocol from multiple transport protocols to initiate handoff of the user equipment from the first wireless network to the second wireless network; and

utilize the selected transport protocol to establish a communication session between the user equipment and the second wireless network.

20. The method as in claim 19 , wherein the selected transport protocol supports SIP (Session Initiation Protocol) signaling to establish the communication session as a voice session between the user equipment and the second wireless network.

21. The method as in claim 19 , wherein the communication management resource is operable to:

implement message retransmission schema to convey lost messages when handing off the user equipment from the first wireless network to the second wireless network.

22. The method as in claim 19 , wherein the notification indicates that interworking exists between the first wireless network and the second wireless network.

23. The method as in claim 19 , wherein the communication session is an IMS (Internet Protocol Multimedia Subsystem) voice session.

24. The method as in claim 19 , wherein the selected transport protocol supports confirmation of a destination receiving transmitted communications.

25. The method as in claim 19 , wherein the notification indicates that interworking exists between the first wireless network and the second wireless network without N26 signaling.

26. The method as in claim 25 , wherein the communication management resource is operable to:

receive the notification of the interworking during registering of the user equipment for use of the first wireless network.
