# SIP 区域

SIP 区域是语音 over IP (VoIP) 硬件和资源的分组，用于管理和路由通话。Zoom 呼叫中心为托管在 Zoom 美国全球服务集群（US01）上的客户提供来自以下数据中心的 SIP 区域和 PSTN 连接，使用户能够根据其位置和需求连接到最合适的数据中心：

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td><strong>北美</strong></td><td><ul><li>美国西部，加利福尼亚州</li><li>美国东部，弗吉尼亚州</li></ul></td></tr><tr><td><strong>欧洲</strong></td><td><ul><li>荷兰，阿姆斯特丹</li><li>德国，法兰克福</li></ul></td></tr><tr><td><strong>亚太地区</strong></td><td><ul><li>澳大利亚，悉尼</li><li>澳大利亚，墨尔本</li><li>日本，东京</li><li>日本，大阪</li><li>新加坡</li></ul></td></tr></tbody></table>

### 区域支持

对于需要数据本地化且位于受支持区域的客户，Zoom 呼叫中心支持区域专属账户。拥有区域专属账户的客户必须从其区域对应的数据中心发起所有通话，且不能使用其账户区域之外的 SIP 区域；不过，如有需要，通话和媒体仍可继续进行国际连接。

以下列表详细说明了 Zoom 呼叫中心支持的区域以及可用的区域专属数据中心位置：

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td><p><strong>欧洲</strong></p><ul><li>德国，法兰克福</li><li>荷兰，阿姆斯特丹</li></ul></td><td></td></tr><tr><td><p><strong>沙特阿拉伯王国</strong></p><ul><li>吉达</li><li>利雅得</li></ul></td><td></td></tr></tbody></table>

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://library.zoom.com/technical-library/zh/shang-ye-ban-fu-wu/zoom-contact-center/zoom-customer-experience/overview/sip-zones.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
