Abstract: Various devices may benefit from simultaneous call session side registrations for voice over long term evolution in a visited network. A method can include receiving a request for a roaming number request at a first enhanced network node, wherein the request comprises a first identifier of a user equipment. The method can also include interrogating a first network node to determine address information of a second enhanced network node associated with the user equipment and relaying the request for the roaming number to the second enhanced network node using the address information. The method can also include receiving the request for the roaming number at the second enhanced network node and allocating a roaming number associated with the first identifier of the user equipment. The method can further include returning the roaming number to the first enhanced network node and providing the roaming number to a second network node.
