An information providing system includes a terminal on the side of a call originator, a terminal on the side of a call terminator, a content server, and an IP network. When the originator makes a call meant for the terminator, the one user terminal on side of the terminator transmits to the other user terminal on side of the originator information on contents to be provided to the latter so as to make the originator specify either contents or an audible ringing tone. As a result, if the originator specifies contents, the contents are provided from the content server to the one user terminal. Conversely, if the originator specifies a ringing tone, then a ringing tone is provided to the one user terminal in a known manner.
