Chinese carriers have strict requirements to allow Voice traffic into their networks.
Nexmo is able to provide voice termination into China, however, this requires a pre-registration process, currently restricted to managed accounts only.
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 account manager to get this set up for you.
Chinese Carriers do not allow marketing calls. Any such traffic will be blocked at the request of the Carrier without warning. Our voice routes to China cannot terminate Call Centre originated traffic either.
