Abstract: An interactive method and web-based system to provide information to leads generated by different forms of advertising and to provide these leads to the client's knowledge to use in the sale of products. The system gathers information in various ways about customers through telephone calls in which information is gathered using audio and DTMF input that is then stored in a relational database to help the client maximize the usefulness of the lead. Interaction with the lead is via the website. All variable data used in the program is stored in a database. The IVR script is built dynamically using snippets of pre-recorded audio played in a sequence along with audio generated by a text-to-speech (TTS) engine. Once the call is completed, the web based system notifies the client of the presence of a new lead via fax and/or email. The client can elect to use the follow-up mail piece to be sent immediately to make sure the customer gets the information from another source, instead of just the IVR system.
