# 自帶電信業者－地端對等互連（BYOC-P）
作為雲端對等連線的替代方案，Zoom Phone 也支援自帶電信業者（BYOC）的地端對等連線（BYOC-P）服務模式，企業可將其內部部署硬體——具體而言，是一台連接至電信業者的會話邊界控制器（SBC）——與 Zoom Phone 的雲端 PBX 系統連接。
採用此服務模式時，企業仍可使用 Zoom Phone 的雲端 PBX 功能，例如通話佇列、自動總機、號碼指派等，而底層的 PSTN 連線則由公司所選擇的供應商負責處理。此服務模式與 Zoom Phone 的雲端對等連線模式（BYOC-C）幾乎相同，差別在於客戶需自行提供並維護其受支援的 SBC，與 Zoom Phone 的資料中心進行對等連線，而非由底層電信業者提供。
#### 在地端對等連線模式下，服務區域由客戶所選擇的電信服務供應商決定
不同於包含一般可服務國家與地區清單的 Zoom Phone 原生服務與雲端對等連線服務，地端對等連線的服務區域則由客戶所選擇的電信服務供應商決定。建議企業與所選擇的電信供應商洽詢，以確保其涵蓋範圍能符合業務需求。

**注意**
Zoom Phone 端點一律會先向 Zoom 資料中心建立連線；然而，BYOC-P 的 SBC 需要雙向連線。若您對連接埠連線與範圍有任何疑問，請聯絡您的 Zoom 技術客戶團隊，以取得有關連線選項的更多資訊。

## 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-tw/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.
