Get a phone number (from ThunderPhone or your own)
Get a ThunderPhone number in seconds, or connect your VoIP provider to use numbers you already own.
Numbers are how callers reach your agent. On Phone Numbers
(/dashboard/phone-numbers), click Add number to see your two
options:
- ThunderPhone number — a real U.S. number from ThunderPhone's pool, live in seconds. It costs $1/month plus a 1¢/minute surcharge and starts as inbound-only. You can request permission to use it for outbound calls.
- Connect VoIP provider — import numbers you already own, or provision new ones, through your own provider. These numbers support outbound calls and campaigns without requesting ThunderPhone-number access.
The ThunderPhone path
- Choose ThunderPhone number
In the Add-number chooser, pick ThunderPhone number.
- Pick who answers
Select the agent that answers this number and (optionally) a preferred area code.
- Get the number
Click Get number. The number appears in your table and is ready to take calls within seconds.
Provisioning auto-routes the number to your agent — the Inbound select on the number's row shows who answers, and you can change it anytime.
The VoIP path
Connect VoIP provider takes you to Connections → VoIP — the full flow is covered in Connect a VoIP provider. In short, two routes:
- Connect a provider you already use: paste an API key for Twilio or Telnyx, or pick SignalWire, Vonage, Plivo or Other provider to fill in SIP trunk details, with provider-specific steps for the named ones and a Generate AI Setup Guide button for any trunk. Both end with a connection test.
- Set up a new Telnyx account: a step-by-step flow that walks you through creating a Telnyx account, generating an API key, and connecting, with a Connect & Test check at the end.
Once connected, import the numbers you want; imported numbers support inbound and outbound. The programmatic version of this flow is Bring your own numbers (API).
Manage your numbers
Each row in the numbers table gives you:
- Copy the number, and a label field to name it.
- Routing mode and the Inbound agent select.
- An actions menu (⋯) for everything else, including release.
Label phone numbers
In Phone Numbers, select Add label beside a number, enter 1–100 characters, and save. Use Edit label or Remove label to change it later. Labels are shared across your organization and can also identify external caller or destination numbers from call history. They appear in call details and under Exclude numbers from analysis in AI reports. Developers can manage the same E.164-based labels with the Phone Number Labels API.

Dial the number from your own phone and talk to your agent. Or run a simulation and let an AI caller do it.
