Abstract
A network node receives a registration message, where the registration message is associated with registering a user equipment (UE) with a call signaling network for sending or receiving calls. The network node receives a notification message from a call session control node in the call signaling network, where the notification message indicates whether the UE is currently provisioned to engage in calls via a Voice over Long Term Evolution (VoLTE) network. The network node causes calls to or from the UE to be routed via the VoLTE network if the notification message indicates that the UE is currently provisioned to engage in calls via the VoLTE network, and causes calls to or from the UE to be routed via a legacy network, that is different than the VoLTE network, if the notification message indicates that the UE is currently not provisioned to engage in calls via the VoLTE network.
