#   Overview

The **Voice Communication** section covers how your AI agent connects to and interacts with voice communication systems.

It enables handling inbound calls, integrating with telephony providers, and managing voice-based interactions through different protocols and infrastructures.

***

## What You Can Do

With telephony integrations, your system can:

* receive incoming calls
* route calls between agents or systems
* connect to external telephony providers
* handle voice-based customer interactions
* integrate with SIP and traditional phone networks

***

## Key Concepts

Telephony is built on several core technologies and standards:

* **SIP (Session Initiation Protocol)** — used for establishing and managing voice sessions
* **SIP Trunk** — connects your system to telephony providers over the internet
* **PSTN (Public Switched Telephone Network)** — traditional phone network

Each of these is explained in detail in the subpages.

***

## How It Works

A typical telephony flow:

1. A call is received or initiated
2. The system connects through a telephony provider
3. Voice interaction is handled by the AI agent
4. The call can be routed, transferred, or processed

***

## Use Cases

Telephony is commonly used for:

* call center automation
* voice assistants
* inbound customer support
* outbound notifications and campaigns
* call routing and forwarding

***

## Best Practices

* configure integrations before enabling call flows
* validate phone numbers and routing rules
* handle fallback scenarios (e.g., transfer to human)
* monitor call quality and connection stability

***

## Notes

* telephony behavior depends on your provider
* SIP and PSTN may have different limitations
* proper configuration is required for reliable operation
