    Abstract: A dial prompt system and method are provided, which comprise a detecting unit (104) and a dial prompt information processing unit (108), the detecting unit (104) is used to detect whether a dial prompt information is need to be sent to a user (101), if so, the detecting unit (104) triggers the dial prompt information processing unit (108); the dial prompt information processing unit (108) determines the relative dial prompt information to the said user (101) based on the preset policy and sends it to the said user (101). After the present invention is applied into communication system (102), when user (101) sends calling request (such as offhook), the communication system (102) will generate at lest one of voice information, test information, picture information and video information, as the prompt information to allow the user (101) to initiate a call, I.e. at lest one of the voice information, test information, picture information and video information can form multiple information to replace the single dial prompt audio signal.
