A system automates interface intervals with remote telephone terminals as to provide information or advice in response to select tone signals formed at a telephone terminal, and at the conclusion of an interval provides a disconnect or termination signal prompting a caller to 'hang up'. Disconnect signals simulate known sounds, specifically as the 'click' attendant a remote 'hang up' and the traditional dial tone. The disconnect signals are transmitted to a caller after an interface interval to prompt the caller to 'hang up' and release the telephone line connection.
