What is the function of CRBT?

CRBT (Color Ring Back Tone) is the abbreviation of "Color Ring Back Tone", which is a service for the called customer to set special sound effects (music, songs, story lines, character dialogues) for other calling customers who call their mobile phones.

After the called customer opens the CRBT service, when the calling customer dials the user's mobile phone to wait for the connection, it will no longer hear the "beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep

The practical function of extended data is the basic function of CRBT. There are three main functions:

One is the prompt function, which plays the role of prompt. That means that the caller's phone is connected. Please wait a moment.

Another practical function is psychological function. This is the tool function of using telephone between communication subjects. When the phone is waiting, the calling end can hear beautiful or lyrical music set by the called end while waiting. Because of the psychological function of music, callers can release nervous and depressed emotions while waiting to answer the phone, and get some comfort and solace.

The third is the social emergency function. The users of this function are mainly the managers of social public relations-the government. At present, the government has not realized that the notification or broadcasting in the emergency plan can be solved by color ring back tone broadcasting. In case of sudden war, disaster and incident, the government uses CRBT to force broadcasting, covering all callers and realizing accurate information transmission. This function is useless at ordinary times. Once it is enabled, the effect is obvious.
