China Voice Features and Restrictions

Overview

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.

CLI

Once an account gets pre-registered, calls should 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 the international format, for example, 86XXXXXXXXXXX. Contact your account manager if you require local CLI or Voice Proxy support.

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.

Other Features or Restrictions

No limitations beyond those in our Acceptable Use Policy.

中国运营商对允许语音流量进入其网络有严格的要求。

Vonage能够提供进入中国的语音终端，但需要提前对使用范例进行报备。目前语音终端仅限于托管账户(非自助用户)使用。 默认情况下，所有未注册的语音流量都将被拦截。 如果您想向中国发送语音流量，请联系您的客户经理。

主叫线识别 CLI

进行范例报备后，使用我们的语音产品时应从国际、非中国号码拨打电话。 我们的产品为国际号码（国际格式）的呼叫提供 CLI ，但不支持国际格式的中国号码，例如86XXXXXXXXXXX。 如果您需要本地 CLI 或语音代理支持，请联系您的客户经理。

内容

中国运营商不允许意外访问、未经用户同意的营销和短时间语音拨打（语音拨打时间少於15秒，例如语音密码）。 应运营商的要求，任何此类流量都将在没有警告的情况下被拦截。 即使是针对客户现有的客户数据库中的用户或其现有活动或计划的会员，也不允许主动拨打营销电话，除非：

• 客户已从选择接收呼叫的终端用户那里获得同意。
• 每当我们收到运营商的投诉时，客户必须在 24 小时内应要求将数据保存并提供给 Vonage。

其他功能或限制

除了我们可接受的使用政策中的限制，没有其他限制.
