Marketing of goods and services on telephone lines and during a period from the commencement of a telephone call to the receipt and acceptance of that call (quiescent period) when the recipient of the call actuates his or her telephone. This quiescent period of time, during which a ringing signal is normally generated, is used for presentation of advertising or promotional messages, primarily to a caller, although it can be delivered to the recipient of the call, or both. In addition, the system provides for the use of messages during the normal ringing cycle time to effectively replace the ringing signal. The particular advertising or promotional message can be selected for a certain area, such as an area covered by a telephone switchboard or a certain party or characteristics of that party. In this way each individual telephone switchboard is capable of presenting a message different from the next telephone switchboard.
