VoIP Group Call Routing via User Account Mapping

The patent segments the association between telephone numbers and devices by introducing an intermediate structure (user accounts and device groups) that decouples the direct one-to-one mapping. This allows a single telephone number to be associated with multiple devices through shared user accounts, enabling flexible call routing to multiple devices simultaneously while maintaining manageable system complexity through structured organization.

The patent introduces user accounts as intermediary entities that mediate between telephone numbers and multiple IP telephony devices. Instead of directly managing complex many-to-many relationships between devices and telephone numbers, the system uses user accounts as a intermediary layer that simplifies device registration and management. Devices are associated with user accounts, and user accounts are associated with telephone numbers, creating a manageable hierarchical structure.

The patent implements dynamic call routing where the system can adaptively determine which devices to ring based on various factors such as user preferences, device availability, and call handling rules. Instead of statically routing calls to all associated devices simultaneously, the system dynamically selects and routes calls to appropriate devices, reducing unnecessary network traffic and resource consumption while maintaining user accessibility.
