> Give your Vio agent a phone line — import a Twilio number or connect your own carrier over a SIP trunk (BYOC) — and assign the agent that answers.

# 3. Connect a phone number

An agent can't take a call until it has a number. Vio supports two ways to get one: **import
a Twilio number** (fastest) or **connect your own carrier** over a SIP trunk (BYOC).

<Steps>

### Choose how you'll connect

- **Import a Twilio number** — if you have (or buy) a number on Twilio, import it into Vio
  and inbound calls reach your agent immediately. One click also enables **outbound** through
  Twilio's Elastic SIP Trunk.
- **Bring your own carrier (BYOC)** — point your existing carrier or PBX (for example
  FreePBX) at Vio over a SIP trunk. Vio issues you inbound credentials, and you provide an
  outbound host so Vio can dial through you.

<Callout type="info">
Not sure which to pick? Start with Twilio to get live in minutes; move to BYOC later when you
want to keep your existing numbers or carrier rates. Full detail:
[**Phone numbers**](/vio/telephony/numbers) and [**SIP trunks (BYOC)**](/vio/telephony/sip-trunks).
</Callout>

### Add the number

Open **Numbers** in the sidebar and either **Import Twilio** or attach a DID to a connected
**SIP trunk**. The number then appears in your list.

### Assign the agent

On the number, choose the agent that should answer. If you leave it unassigned, your
workspace's default agent answers instead. That's it — inbound is now live.

### Where to next

Before you hand the number to real callers, talk to the agent yourself.
