# Build your first phone agent in 5 minutes
> Step-by-step guide to create, test, and deploy your first AI phone agent.
Create a working phone agent by setting its role, voice, greeting, and deployment path. This guide keeps the setup focused so you can make your first test call in a few minutes.
## Before you start
You need access to an Agni workspace. If you have not signed in yet, follow [Authentication](/guides/authentication) first.
For live phone deployment, you also need a connected phone number. You can still create and test the agent in your browser without one.
Build the agent and define how it should handle calls.
Run a browser call before you send the agent to real callers.
Connect the agent to a number or campaign when it is ready.
## Create the agent
From the Agni dashboard, click **Agents** in the sidebar.
Click **+ New Agent** to open the agent builder.
The builder gives you a prompt editor, model controls, voice settings, and test tools in one workspace.
In the prompt editor, describe the agent's role, tone, goal, and boundaries.
Use this starter prompt for your first test:
```text theme={null}
You are Ava, a helpful phone agent for a dental clinic.
Your goal is to greet callers, understand why they are calling, and help them book an appointment.
Ask one question at a time.
Keep responses under two sentences.
If the caller asks for medical advice, explain that a dentist will help them during the appointment.
Confirm the caller's name, preferred date, preferred time, and phone number before ending the call.
```
Open the model selector and choose the model you want the agent to use.
For a first agent, choose the default recommended model unless you already know you need a faster or more specialized option.
Choose a voice that matches the caller experience you want.
Click a voice to preview it, then select it for the agent.
Open the **Welcome Message** settings and choose how the agent starts the call.
For your first agent, use a direct greeting:
```text theme={null}
Hi, this is Ava from Bright Dental. How can I help you today?
```
Keep the first version small. Add tools, knowledge bases, and advanced call handling after the agent can complete one simple conversation well.
## Test the agent
Use a browser call before connecting the agent to a phone number. This helps you catch prompt issues without spending telephony credits.
In the agent builder, open the testing panel.
Select **Web Call**, then start the call from your browser.
Speak like a real caller. For example:
```text theme={null}
Hi, I need to book a cleaning for next Tuesday afternoon.
```
Check whether the agent asked for the right details, stayed on task, and ended the call clearly.
If the agent gives long answers, add a prompt rule such as `Keep responses under two sentences.` If it skips required details, list those details explicitly in the prompt.
## Deploy the agent
Once the browser test works, connect the agent to a real calling path.
Open [Phone Numbers](/guides/phone-numbers) and buy, import, or connect a number.
For incoming calls, create an inbound rule and assign the phone number to your new agent. See [Inbound Calls](/guides/inbound-calls) under Campaigns for the full setup.
For outbound calls, add the agent to an outbound workflow after you have contacts and caller ID ready. See [Outbound](/guides/campaigns) under Campaigns for the workflow.
Call the number or launch a small test campaign. Confirm that the agent answers, follows the prompt, and captures the outcome you expect.
