Abstract: Embodiments are provided for notifying an electronic device connected to a non-terrestrial communication network of a voice-based communication request that is intended for the electronic device. According to certain aspects, a data center can receive the voice-based communication request that is initiated by an originating device. The data center can generate a text message that indicates the voice-based communication request and transmit the text message to the non-terrestrial communications network for delivery to the destination electronic device. The text message can identify the originating electronic device and enable the user of the destination electronic device to send an additional text message to the originating electronic device.

Abstract: Embodiments are provided for processing a voice-based communication request intended for a destination electronic device that is connected to an on-board communications network. According to certain aspects, a data center can receive the voice-based communication request that is initiated by an originating device. The data center can determine that the destination electronic device is registered with the on-board communications network and generate an audio unavailable message that indicates the unavailability of the destination electronic device. Using a communication channel that is established with the originating electronic device, the data center transmits the audio unavailable message to the originating electronic device to inform its user that the voice call cannot be connected.
