in response to the call request originating outside of the MNO, routing, by the MNO network, the call request through an established default bearer ([0105]: subscriber making call from a visiting network and routing call accordingly through a default bearer, like a proxy CSCF: [0107]).
Regarding claims 2 and 12, Yau discloses wherein the call request originated on a roaming network ([0104]: subscriber making call from a visiting network).
Regarding claims 3 and 13, Yau discloses wherein the call request is routed through the established default bearer rather than a dedicated bearer ([0105]: subscriber making call from a visiting network and routing call accordingly through a default bearer, like a proxy CSCF: [0107]).
