User interfaces may enable users to initiate voice-communications with voice-controlled devices via a Wi-Fi network or other network via an Internet Protocol (IP) address. The user interfaces may include controls to enable users to initiate voice communications, such as Voice over Internet Protocol (VoIP) calls, with devices that do not have connectivity with traditional mobile telephone networks, such as traditional circuit transmissions of a Public Switched Telephone Network (PSTN). For example, the user interface may enable initiating a voice communication with a voice-controlled device that includes network connectivity via a home Wi-Fi network. The user interfaces may indicate availability of devices and/or contacts for voice communications and/or recent activity of devices or contact.
