After you activate a number, carriers require you to ensure the inbound link is clear and to configure playback content. You must configure inbound call playback to meet compliance requirements for preventing telecom fraud and managing inbound calls. This helps you avoid service interruptions caused by number suspension. If you do not complete the configuration before 10:00 on June 1, 2026, the platform applies default rules for inbound calls and playback. These rules may incur charges. This topic describes two configuration methods: self-service configuration using the Interactive Voice Response (IVR) tool in the console, or contacting service personnel for assistance.
Inbound call playback configuration details
To prevent telecom fraud and standardize number usage, carriers require number users to ensure a clear inbound link. You must also configure inbound call playback. This ensures that when a user calls your number, they hear a preset audio message instead of a busy signal.
After you activate a number, complete the inbound call playback configuration using one of the following methods.
Method 1 (Recommended): Self-service configuration using the IVR tool in the console
Method 2: Contact service personnel for assistance
Method 1: Self-service configuration using the IVR tool in the console
Log on to the Voice Service console.
In the navigation pane on the left, choose . The Real Number Management page displays a compliance reminder for inbound call playback at the top. When you first visit the page, a "Configure IVR Playback Feature" pop-up window appears.
In the compliance reminder at the top of the page, click Inbound Call Playback Configuration. Alternatively, close the pop-up window and choose in the navigation pane on the left.
On the Inbound Configuration page, configure a global playback file or a playback file for a specific number:
Global configuration: Click Modify Global Configuration. Set parameters, such as Configuration Type, Playback File, and Configuration Description. Then, click Confirm Modification.
Specific number inbound configuration: Click Add Specific Number Inbound Configuration. Set parameters, such as Configuration Type, Qualification Type, Company, Called Number, Playback File, and Configuration Description. Then, click Confirm Add.
Method 2: Contact service personnel for assistance
If you cannot complete the configuration on your own, you can contact your account manager or submit a ticket. Provide your account information and the numbers that require configuration. Service personnel will help you complete the setup.
Consequences of not configuring inbound call playback
If you do not configure inbound call playback promptly, carriers may restrict your number and make it unusable.
The platform will start applying default inbound call answering and playback rules at 10:00 on June 1, 2026. These rules may incur charges. For pricing details, see Pricing of Voice Service for mainland China or contact operations personnel.
If you do not agree to the default rules, you can unregister the number.
