Techniques for transmitting information to a recipient under their control are described. In some situations, the techniques are used in conjunction with a fax delivery system to provide, as part of a connection established to perform a fax transmission, a variety of functionalities to a human recipient that is participating as part of the connection, such as when the human recipient is contacted in error. In addition, in some situations, an interactive voice response system is used to receive and interpret input from a human recipient, such as in response to one or more control selections or options provided to the human recipient.
