# Dapta Phone Call
Our Dapta Phone Call nodes work as a direct connection to our AI Voice agents. They allow you to connect remotely to the agent via a flow in the Flow Studio and send variables to your voice agent.
To access the node, we are going to open the Flow Studio and add the node to the canvas
Once you open the node you can set a “From” phone number as well as a “To” from number. It’s important to take into account these following points:
* The from number NEEDS to be a registered phone number. That one is by default Dapta’s phone number but if you want to send calls from a number of your choosing, you have to register your phone number on the Voice Agents>Phone number section
* Numbers ALWAYS need to start with a +
* Numbers should ALWAYS have the country code
You can then select the agent you want your calls to use
And finally you can set your dynamic variables. These are the parameters that the agent will replace in the prompt so that conversations can be personalized.
You can select any variable that you have defined in your agent’s prompt inside brackets {{}}
Now you’re all set! Every time the flow will be executed, the agent will call that number and replace the variables for the values you set.
You can also set those variables to be dynamic by clicking on the top right button of the input field
There you can set it to any other node located in the flow studio and connected to the Dapta Phone call node.

## 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://docs.dapta.ai/flow-studio/nodes/dapta-phone-call.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.
