However, existing studies are primarily designed for single, explicit goal completion, while phone call assistants face a proxy setting that requires coordinating the device owner's explicit preset goal with the caller's implicit and dynamic goal.

It covers regular presets, emergent presets, and no-preset cases, and includes diverse relations between
