Phone numbers
Phone numbers connect your agents to the telephone network — get a number, attach a voice agent, and it answers inbound calls and can place campaign calls.
Open Build → Phone numbers. The top of the page shows how many of your agents answer calls, and how many of them have a number — if some don't, that count is highlighted.
Where numbers come from
Buy from Callable
The simplest path. Search for a number on the page, pick one and pay once — it's set up, attached to your agent and wired for inbound calls automatically. There's no telephony account of your own to create.
Bring your own: Twilio, SignalWire or Vonage
If you already have an account and numbers with one of these:
- Go to Integrations and connect the account.
- Back on Phone numbers, the Bring your own card names what's connected, and a switcher appears above the number list — Callable numbers or your own provider.
- Import the numbers you already own, or buy new ones on your own account.
On Vonage, use Test connection in its Integrations card after saving your API key and secret. See Vonage.
SIP trunk
If your numbers are with a carrier or PBX that isn't listed, keep them there and point your trunk at Callable. See SIP trunking.
Your numbers
The Your numbers list shows each number you own with its capabilities (voice, SMS) and whether it's attached. Pick an agent from Attach to agent… and the number is wired to that agent in one click — no webhook to copy. Reattach to… moves it to a different agent.
To have a whole agent team answer a number, open the team in Agent Teams and set its Answers on phone number field. See Agent Teams.
Texting (SMS)
US carriers only deliver business texts from a verified sender. The Texting (SMS) section on this page is where you verify yours, once, before an SMS campaign. See A2P 10DLC & sender verification.
Advanced: connecting a number by hand
When a Twilio or SignalWire account is connected, an Advanced section appears at the bottom with each agent's webhook URLs — for debugging, or for numbers you manage in your provider's console:
- This agent's webhook — always reaches that agent, whichever number was called. Paste it into the number's A call comes in setting (HTTP POST).
- Shared webhook — picks the agent by matching the called number against the agent's Phone number field.
Callable numbers never need this; they wire themselves.
Outbound caller ID
For campaigns, your numbers are what contacts see. You choose the number when you create a campaign, and calls go out from it. The same number can answer inbound calls through its attached agent and place outbound campaign calls.
