A Voice over Packet (VOP) application meets the challenges of combining legacy voice networks and packet networks by allowing both voice and signaling information to be transported over the packet network.
Internet protocol multimedia subsystem de-registration methods and systems
Methods and systems provided herein provide for IMS de-registration when a roaming network does not support voice over long term evolution (VoLTE) or voice over new radio (VoNR). An IMS de-registration system can trigger functionality in a home subscriber server and / or a unified data management (UDM) function to trigger de-registration from the IMS. The system may trigger identification of a non-voice over packet switched (non-VoPS) network and further trigger de-registration based on this identification.
