# 自带运营商 – 本地对等互联（BYOC-P）
作为云对等的替代方案，Zoom Phone 还支持自带运营商（BYOC）本地对等（BYOC-P）服务模式，在该模式下，企业将其本地硬件——具体来说，是连接到运营商的会议边界控制器（SBC）——与 Zoom Phone 的云 PBX 系统相连。
在这种服务模式下，企业继续能够访问 Zoom Phone 的云 PBX 功能，例如呼叫队列、自动接待员、号码分配等，而底层 PSTN 连接则由公司所选的提供商负责处理。此服务模式与 Zoom Phone 的云对等模式（BYOC-C）几乎相同，唯一不同之处在于，客户提供并维护自己受支持的 SBC，以便与 Zoom Phone 的数据中心建立对等连接，而不是由底层运营商提供。
#### 在本地对等中，服务区域由客户所选的电话通讯服务提供商决定
与原生构建的 Zoom Phone 解决方案和云对等服务不同，这些服务包含适用国家和地区的一般列表，本地对等服务区域由客户所选的电话通讯服务提供商决定。建议企业咨询其所选电话通讯提供商，以确保其覆盖范围能够满足企业需求。

**注意**
Zoom Phone 终端始终会主动发起到 Zoom 数据中心的连接；然而，BYOC-P 会议边界控制器需要双向连接。如果您对端口连接性和范围有疑问，请联系您的 Zoom 技术账户团队，以获取有关连接选项的更多信息。

## 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/zoom-workplace/zoom-phone/zoom-phone-bluepaper/overview/bring-your-own-carrier-premises-peering-byoc-p.md?ask=&goal=
```
`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.
