A Ring back tone is the tone a caller hears when he/she places a call to another fixed line number, or mobile terminal. It is generated, not by the called party’s terminal or handset, which is what, happens with ring tones, but by a signaling capability within the called party’s network service provider. Its attraction lies in the fact that it can be personalized (like a ring tone, with which it should not be confused). It could be a tone, a particular sound, or a collection of sound effects, bars of music, even voice, or quite conceivably some time soon, multi-media messages (and perhaps images).
Also and therein lies its great attraction, Ring back tones are under the complete control of the network operator, although they are only one application among several others that presently come under the heading of “audio streaming”.
WiFi Network’s Ring back Tone enables users to select a melody or record a short greeting that the caller will hear. This service works with any mobile terminal unlike ring tone services that need to be stored in specific mobile terminals. Specific melodies can be designated according to time of day, date, caller's number or caller's number group. A pre-recorded message can also be played as well. Also, users may send a selected melody to another user as a gift.
