Supporting termination access domain selection for a dual registered wireless device

A method comprising:

• sending, by an application server to a subscriber server, a request message indicating a first query for terminating access domain selection (T-ADS) information for an Internet protocol multimedia subsystem (IMS) session of a wireless device;
• receiving, by the application server from the subscriber server, the T-ADS information comprising:
• a first wireless device Internet protocol (IP) address and a first network name of a first radio access technology (RAT) for the IMS session;
• and
• a second wireless device IP address and a second network name of a second RAT;
• determining, by the application server, an access network for the IMS session based on the first network name, the first wireless device IP address, the second network name and the second wireless device IP address, wherein the access network is one of the first RAT or the second RAT;
• and
• sending, by the application server to the wireless device, an IMS message to setup the IMS session over the access network.
