# How Phone Numbers Work

> Understand how Tala manages phone numbers for your voice agents

## Overview

Tala provides phone numbers that your voice agents use for calls. You don't need to set up your own telephony provider - we handle everything for you.

## Key Concepts

### Managed Phone Numbers

Unlike traditional solutions where you bring your own phone system, Tala provides ready-to-use phone numbers:

* **No setup required**: Numbers are pre-configured and ready to use
* **Reliable infrastructure**: Enterprise-grade telephony handled by us
* **Simple billing**: Included in your subscription

### Inbound vs Outbound

  </Card>

  <Card title="Outbound Calls" icon="phone-arrow-up-right">
    Your voice agent calls customers (campaigns, reminders, follow-ups)
  </Card>
</CardGroup>

## Number Assignment

Each phone number is linked to:

1. **Your organization**: Only your team can use it
2. **A workflow** (for inbound): Determines which agent answers
3. **Outbound calls**: Used as the caller ID

### How Inbound Calls Work

```
Customer dials your Tala number
        ↓
Tala routes the call
        ↓
Your voice agent answers
        ↓
Conversation begins
```

### How Outbound Calls Work

```
You trigger a call (campaign or API)
        ↓
Tala places the call using your number
        ↓
Customer sees your Tala number as caller ID
        ↓
Your voice agent handles the conversation
```
