Problems solved by technology

[0015] It can be seen from the description of the realization process of the color ring back tone service above that the color ring back tone customized by the called party is played directly to the calling party without judging the current status of the called party. The call cannot be connected to the called party at all, so that the colored ring back tone that has been played becomes a kind of wrong information provided to the calling party, causing the calling party to be unable to communicate with the called party after waiting for the current call to be connected; A possible situation is that when the called party is in a busy or non-idle state, the IP has played the corresponding color ringback tone to the calling party, but after the SSP paging failed to call the called party, it will play the corresponding failure prompt tone to the calling party. The audio before and after the caller is inconsistent; and in order to prevent the ICA operation in step 109 from repeatedly triggering the smart service, the ICA operation must be extended, but the modification of the ICA operation is a non-standard protocol, which may easily lead to difficulties in docking tests
