# Phone Number

> A dedicated phone number with an AI receptionist for calls and text messages

The phone side of Sontairo Voice gives your business a dedicated phone number. An AI receptionist answers around the clock — naturally, in real time — and replies to text messages, so callers get help even when no one is available.

## Activate your number

1. Open the **Voice** page
2. Optionally enter a **preferred area code**
3. Click **Activate Voice**

You get a dedicated US local number. Once active, the page shows your number with **Copy** and **Call your agent** buttons.

<Info>
  Activation requires the **ADMIN** role and a Voice-enabled plan (the Voice add-on, or an Ultra/Enterprise plan). Numbers are US-local at launch.

## What it does

* **AI call answering** — inbound calls are answered by a real-time voice AI that handles public questions about your business
* **Two-way SMS** — the AI replies to inbound text messages, and standard carrier keywords like STOP and HELP are honored
* **Shared history** — call transcripts and conversations are saved to your workspace chat history, so you can review what customers asked

The AI only shares caller-safe, public-facing information — your private workspace data stays private.

## Usage at a glance

The Voice page shows your last 30 days of activity: **Calls**, **Call minutes**, and **Text messages**.
