Systems and methods use mobile telephones as input devices for recording audio messages on a server. A user inputs a first feature code into the mobile telephone and the feature code is sent to a mobile switching center (MSC). The MSC maps the feature code to a server and forwards the feature code and a user identification to the server. Once the mobile telephone is connected to the server, the user can record his audio message. The user can later retrieve the recorded audio message by inputting a second feature code into the mobile telephone. The second feature code is also assigned to the server. The recorded message is played after the mobile telephone is connected to the server.
