# Twilio (SMS & phone)

> Reach members by SMS or a voice call for high-urgency events.

Twilio powers Clarion's **SMS** and **phone call** channels. Both are for urgency rather than interaction: an SMS or a call gets a human's attention, and the conversation continues in Clarion, Slack, or Teams.

<Note>
  Twilio is configured by your Clarion platform administrator, not per workspace. If the integration page says Twilio is not yet configured, contact your administrator.
</Note>

## Prerequisites

* Twilio enabled for your Clarion instance
* Workspace members with a **verified phone number** on their profile

## Connect

1. In Clarion, open **Integrations** and find **Phone**.
2. Click **Connect**.
3. Send a **test SMS** or place a **test call** to a member to confirm delivery.

Members set their own phone number in their profile — see [Members](/learn/settings/members). A member without a number cannot be reached by SMS or call and will not appear in the picker.

## As a notification destination

SMS can be selected as a [notification destination](/learn/notifications/introduction), targeting one or more workspace members.

<Warning>
  SMS is **notification only**. It carries no interactive approval buttons, so an approval request delivered by SMS still has to be answered in Clarion, Slack, or Teams. Pair SMS with an interactive channel rather than using it alone.
</Warning>

## What agents can do

| Tool                     | What it does                             |
| ------------------------ | ---------------------------------------- |
| `send_sms_to_member`     | Text a workspace member                  |
| `make_call_to_member`    | Place a voice call to a workspace member |
| `list_workspace_members` | List members reachable by phone          |

Both send actions are scoped to workspace members — an agent cannot dial an arbitrary number.

## Disconnect

Click **Disconnect** on the integration page. SMS destinations stop delivering and the phone tools disappear from agent skills.
