# Get a phone number (/docs/get-a-number)

> Four ways to get a phone number for your AI agents. Buy one from OmniDimension, or import your own from Twilio, a SIP carrier, or Exotel.

Every AI agent that makes or receives calls needs a phone number. You have
four ways to get one. If you don't already have a number with another
provider, buying one from OmniDimension is the fastest path. If you already
own numbers, import them.

  Buying a number takes a couple of minutes and needs no external account.
  Only import if you already have numbers you want to keep using.

## Import from Twilio [#import-from-twilio]

If you already have Twilio numbers, import one directly with your Twilio
account SID and auth token. No SIP trunk setup required.

## Import via SIP [#import-via-sip]

OmniDimension speaks SIP, the standard protocol every modern carrier
supports. If your carrier can hand out SIP trunk credentials, you can plug
it in. We have quick-start guides for RingCentral, Vonage, and Twilio's SIP
trunking.

## Import from Exotel [#import-from-exotel]

If you're on Exotel, you can import an Exotel number after building a call
flow in your Exotel dashboard.

## After you have a number [#after-you-have-a-number]

Attach it to an agent from the **Phone Numbers** page in your dashboard, then
make a test call. See [Configure your agent](/docs/dashboard-guides/configure-your-agent)
to set up how it handles calls.
