Devices with support for virtual assistants, such as smart displays, smart speakers, etc. include features that enable users to place audio or video calls to their contacts. The calling features are restricted to the user that is logged in to the device, since contacts are private to the user. This disclosure describes techniques to enable other users to place calls. A user, such as a device owner, can configure their address book to mark a subset of their contacts as public contacts. Public contacts are accessible to other users, who can then place calls to such contacts.
