Chinese carriers have strict requirements to allow Voice traffic into their networks.
Syniverse is able to provide voice termination into China, however, this requires a pre-registration.
Once an account gets pre-registered, calls will be sent from an international, non-China number when using our Voice products. Our product does offer CLI delivery for calls delivered from international numbers (in international format), but not from China numbers in international format (e.g. 86XXXXXXXXXXX). If you require to use your own international CLI, please contact your Syniverse account manager to understand the requirements so they can get this set up for you.
Chinese carriers do not allow marketing with cold calling. Any such traffic will be blocked at the request of the operators without warning. Unsolicited marketing calls are not allowed even towards users in customer's existing customer database or members of their existing campaigns/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 Syniverse upon request within 24 hours whenever we receive complaint from the Carriers.
