# Callflow

In a basic configuration there are only two requirements for our telephony to work: 

1. A central Omnidesk number for your customers to call (see [Numbers](/omnidesk/telephone/numbers.md#numbers), in the sample below: +13512312311). 
2. An agent with a browser or phonenumber.

That's it.

The following image shows how the callflow to Omnidesk can be configured (with in order: step 1, 2, 3):

# Agent Instructions: 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:

```
GET https://docs.omnidesk.io/omnidesk/telephone/callflow.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
