Abstract:
A device is configured to detect an emergency call from a user device associated with a device identifier, the device identifier including information that identifies the user device. The device is configured to detect that the user device is not associated with a valid originating telephone number, based on detecting the emergency call. The device is configured to determine a temporary originating telephone number, based on detecting that the user device is not associated with a valid originating telephone number, and to store an association between the device identifier and the temporary originating telephone number. The device is configured to transmit the emergency call, with information identifying the temporary originating telephone number, to an emergency call device, the temporary originating telephone number permitting the emergency call device to place a return call to the user device.
