# Import Existing Number

Import Existing Number lets you connect a phone number you already own to a Voicetta agent.

The number stays billed on your carrier account (Twilio, Vonage, Telnyx, or another SIP provider). Voicetta does not buy or port the number for you.

## Why it matters for your business

- Keep numbers you already use with Guests.
- Avoid buying a second line when you only need Voicetta answering.
- Use your existing carrier contract and compliance setup.

## Before you start

You need:

- an agent in Voicetta,
- owner access to the workspace,
- the number in E.164 format (for example `+14155550123`),
- credentials for the provider that owns the number.

## Providers

### Twilio

1. Open **Phone numbers** → **Add** → **Import Existing Number**.
2. Choose **Twilio**.
3. Enter the number, Account SID, and Auth Token.
4. Leave SMS off unless Voicetta has told you SMS webhooks are ready for Twilio.
5. Import, then place a test call.

Voicetta updates the Twilio voice webhook automatically so inbound calls reach your agent.

### Vonage

1. Choose **Vonage**.
2. Enter the number, API key, and API secret.
3. After import, complete the SIP voice setup shown in the success message so Vonage dials Voicetta LiveKit.

### Telnyx (your own account)

1. Create a dedicated Telnyx API v2 key for Voicetta.
2. Choose **Telnyx**.
3. Enter the E.164 number and API key.
4. Import.

Voicetta then:

- confirms the number belongs to that Telnyx account,
- finds or creates a Telnyx FQDN connection named **Voicetta LiveKit** on **your** Telnyx account,
- points that connection at Voicetta’s LiveKit SIP host,
- assigns your number to the connection,
- attaches LiveKit routing for the agent.

You do **not** paste a Telnyx connection ID.

### BYO SIP trunk

1. Create a SIP trunk in Voicetta with your provider gateway host and optional username/password.
2. Attach the DID to that trunk.
3. Configure your SIP provider to send inbound calls to Voicetta LiveKit for that DID.

## After import

- Confirm the number appears on **Phone numbers** with the correct source badge.
- Assign the agent if needed.
- Enable inbound routing and place a test call.
- Enable outbound only when you need outbound calling from that number.

## Deleting an imported number

Deleting in Voicetta removes Voicetta routing and local records only. The number stays on your carrier account.

## Common mistakes

- Using Voicetta’s purchase Telnyx key instead of **your** Telnyx API key.
- Entering a number that is not on the credentialed account.
- Expecting carrier porting (LOA/FOC) — this flow is import/BYO, not porting.
- Enabling Twilio SMS before Voicetta SMS webhooks support Twilio.

## Notes

- Import is not carrier porting. Deleting an imported number keeps the DID on your carrier.
- Twilio SMS Enabled should stay off until Twilio SMS webhooks are supported.
- Telnyx outbound calling may still require an Outbound Voice Profile on your Telnyx account.
