# Getting Started with Voice Gateway
> Step-by-step guide to set up Voice Gateway, including creating voice Flows, configuring Endpoints, and routing contact centers or phone numbers to your AI Agent.
## How to Set Up Voice Gateway?
To set up Voice Gateway, do the following steps:
1. [Create a Voice Gateway Flow](#create-a-voice-gateway-flow)
2. [Create a Voice Gateway Endpoint](#create-a-voice-gateway-endpoint)
3. [Route Contact Centers or Phone Numbers to Voice Gateway](#route-contact-centers-or-phone-numbers-to-voice-gateway)
4. [Set up Voice Gateway for your Organization](#set-up-voice-gateway-for-your-organization)
## Create a Voice Gateway Flow
Start your **Voice Gateway** project by creating a voice-enabled flow. With a voice conversation, the AI Agent must respond with a text-based message for every user input. Voice conversations happen on a turn-by-turn basis, meaning that Voice Gateway bundles all dialogue outputs triggered by the Flow into one message and delivers it across the phone line.
Every Cognigy.AI node that offers text-based messages can be used in a voice flow. If you have rich media in your flow, the fallback text field will be used as voice output.
If there is a Voice Gateway channel-specific configuration, this configuration will be used instead of the one in the default section. In the Voice Gateway channel, you can find pre-defined SSML tags and [activity parameters](/ai/agents/develop/node-reference/voice/voice-gateway/parameter-details).
For voice-specific actions, you can use the [Voice Gateway Flow Nodes](/ai/agents/develop/node-reference/voice/voice-gateway/overview).
## Create a Voice Gateway Endpoint
To do voice-based experiences with your AI Agent, create your [Voice Gateway Endpoint](/ai/agents/deploy/endpoint-reference/voice-gateway) in Cognigy.AI. To do that:
1. In the left-side menu of the Cognigy.AI interface, select a Project where you want to create a voice Flow.
2. In the left-side menu of the Project, go to **Deploy > Endpoints**.
3. On the **Endpoints** page, click **+ New Endpoint**.
4. In the **New Endpoint** section, do the following:
1. Select the **voice-gateway** Endpoint type.
2. Add a unique name.
3. Select a relevant Flow from the list.
5. Click **Save**.
## Route Contact Centers or Phone Numbers to Voice Gateway
To route your Contact Center or Phone Number to your Voice Gateway Endpoint, your SIP Trunk needs to be set up. Get in touch with your Cognigy Business Representative to configure your SIP Trunk and route your number to the right Endpoint.
