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 without prior agreement of the carrier.
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).
All calls will be sent from an international CLI when using our Voice APIs except for SIP. If you require to use your own international CLI, please contact email@example.com so that we can set this up for you.
