How to set the color ring back tone for fixed line?

There are three ways to set the landline ringtone:

1. Call CRBT customer service department to order. There are two kinds of CRBT customer service: manual and automatic. You can tell the customer service staff the name of the song you need.

Second, you can log on to the CRBT website directly. Of course, before logging in, you must use local telephone to call CRBT customers to change CRBT password.

Third, you can use a fixed source phone to dial 10000 to change your phone password, and then log in to the online customer service center, which is connected to the CRBT website.

The best way is to log on to CRBT website and try to listen before ordering. When placing an order, be sure to see the effective time.
