# Caller Based Router

The Callback Based Router allows you to route directly from number to number. This can be from external to extension, extension to external, extension to extension and vice versa. This creates a structured workflow in which you can create the desired routings without any effort.
### Using the Called Based Router
When you want to start routing numbers you need to do the following steps:
1. Navigate to the left menu.
2. Click on Content.
3. Go to Routing Table.
4. Fill in the Caller.
5. Then fill in the designated destination that the caller needs to be routed to.
As you can see in the image above, you see that the **caller**, the person who is calling, is routed to the **target**, or the desired destination. After you connected a public number to your Caller Based Router and start calling this number, the **caller** (+31612345678 in this situation) will be routed to the **target**.

## 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://manuals.dialox.ai/store/legacy-apps/caller-based-router.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.
