Caller ID Guidelines

Overview

International reach:

  • Chinese carriers have strict requirements to allow Voice traffic into their networks.

  • Vonage can provide voice termination in China. However, this requires a pre-registration process currently restricted to managed accounts only. All non-registered traffic will be blocked by default. Contact your account manager if you would like to send voice traffic towards China.

Domestic reach:

  • Domestic Vonage numbers must only be used to place calls via Vonage Voice API.
  • Domestic calls from non-Vonage numbers are best effort.
  • The self-service buying of numbers is not available for China at this time on Vonage's Customer Dashboard. Customers can still request a new number from Customer Dashboard by filling in and submitting the required information or by contacting their Account Manager to start the order. After the request is reviewed and there is no issue, the new number will be reserved for customer.
  • Outbound calls from Toll Free numbers are not supported.
CLI

No limitations apart from Local CLI or Invalid CLIs as explained in In-Country, Local, or No-CLI Calls Rejected

Use-Case & Content Guidelines

Content

Chinese operators do not allow marketing with cold calling and short duration calls (call duration less than 15 seconds i.e. OTP voice). Any such traffic will be blocked at the request of the operators without warning. Unsolicited marketing calls are not allowed even towards users in the customer's existing customer database or members of their existing campaigns or programs unless:

  • Customer has obtained the consent data from the end users opt-in to receive the call.
  • Customer has to keep and provide the data to Vonage upon request within 24 hours whenever we receive complaint from the operators.

No other limitations beyond those in our Acceptable Use Policy.

Other features or restrictions No limitations beyond those in our Acceptable Use Policy.
