# Integrations

> Connect your telephony provider and phone numbers to go live with real calls.

Voicerix connects to your telephony provider so your agents can make and receive real phone calls. All providers are configured from the **Integrations** page in the platform.

## How to Set Up

<Steps>
  <Step title="Go to Integrations">
    In Voicerix, navigate to **Integrations** and click **Add configuration**.
  </Step>

  <Step title="Choose your provider">
    Select your telephony provider from the list and enter your credentials. See the provider-specific pages above for exactly what you need.
  </Step>

  <Step title="Add a phone number">
    After saving the configuration, open it and add at least one phone number (E.164 format, e.g. `+1234567890`). This is the number your agent calls from or receives calls on.
  </Step>

  <Step title="Set default outbound (optional)">
    Mark one configuration as **Default Outbound** so it is used automatically for test calls and campaigns.
  </Step>

  <Step title="Enable inbound (optional)">
    To receive inbound calls, assign an **Inbound workflow** to a phone number. Voicerix will automatically push the webhook URL to your provider. See [Inbound Calling](/configuration/integrations/inbound) for details.
  </Step>
</Steps>

***

## What you can do

* **Outbound calls** — your agent calls contacts from a campaign or test
* **Inbound calls** — your number receives calls and routes them to the right agent
* **Multiple configurations** — add separate configurations for different sub-accounts or providers
* **Multiple phone numbers** — each configuration can hold multiple numbers

***

## Inbound Calling

For inbound calls, Voicerix uses a single org-wide webhook URL. When you assign an inbound workflow to a phone number, Voicerix automatically pushes this URL to your provider — you don't need to set it manually in most cases.

See [Inbound Calling](/configuration/integrations/inbound) for the full setup guide and per-provider instructions.
