The RBT service refers to music or greetings customized by the called party for the calling party. When the calling party calls the subscriber who customizes RBTs, the calling party hears or watches the personalized music or sound rather than the traditional beep tone, and may be impressed by the RBT.
The portal provides a unified window for subscribers to manage the RBT service.
The RBT service includes two services: Audio RBT and Video RBT.
Compared to the audio RBT service, the Video RBT service adds the video function, the user who has customized the Video RBT to your number, the calling party views a personalized video music or a song rather than the traditional ring back tone.
Except the called service described above, there is also Calling service.
