# 开始之前

开始使用 ZPLS。

在网络中部署 ZPLS 之前，需要考虑多个与用户访问、站点设计、信令和媒体以及 PSTN 集成相关的事项，这些都应在部署前加以考虑。以下页面将探讨这些场景。阅读之后，您可以了解高层技术设计的影响，从而指导您的上线部署。

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://library.zoom.com/technical-library/zh/zoom-workplace/zoom-phone/zoom-phone-local-survivability-field-guide/before-you-begin.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
