Your agent can speak and listen over the public telephone network (PSTN) without dealing with SIP trunks or carrier quirks. Operator provides a built-in Twilio integration so you can go live in minutes.

Integration options

Operator‑managed numbers (no Twilio account required)

Provision phone numbers directly from the Operator dashboard (or API, coming soon).

  • Area‑code targeting: Choose the country and area code to give callers a familiar local presence
  • Multiple numbers: Attach as many numbers as you need—for example, one per campaign, product line, or geo
  • SMS enabled: Set up messaging campaigns to enable two-way texting

Bring‑your‑own Twilio

Use your existing Twilio account and phone numbers. Connect under Channels → Phone.

  • Keep existing numbers: No porting hassle; callers keep the number they already know
  • Unified reporting: Usage continues to appear in your Twilio console
  • Full control: Manage CNAM, regulatory bundles, and geo-permissions as usual
  • Branded calls: Brand your outbound calls with your business name, call reason, and logo

Phone number settings

Each phone number in Operator comes with configurable controls to help manage traffic, protect deliverability, and tailor the experience.

Caller filtering

  • Restrict anonymous callers: Block calls with no caller ID
  • Decline non-customer calls: Reject numbers not recognized in your CRM/internal system

Incoming call rollout

  • Rollout percentage: Gradually ramp up traffic; only a set percentage of calls are answered by the agent
  • Forwarding number: Route remaining calls elsewhere (e.g. a live agent or voicemail), or when the agent is disabled

Outgoing call limits

  • Max concurrent calls: Cap how many outbound calls can be active at once
  • Max hourly calls: Throttle outbound volume per hour

Why limits matter – US carriers increasingly police high‑volume or bursty traffic. Setting sensible concurrency and hourly limits keeps answer rates high and reduces call blocking.

Deliverability

For high-volume or outbound-heavy use cases, maintaining phone number reputation is critical. We offer enterprise-grade safeguards to improve reach and minimize call blocking:

  • Spam flag detection: We continuously monitor your numbers to check if they’re being flagged as spam by carriers or third-party apps
  • Reputation-based rotation: If you maintain a pool of numbers, we can automatically cycle underperforming ones out and rotate in fresh numbers
  • Local presence dialing: We can provision numbers with local area codes based on your target region, improving answer rates
  • Trust Hub: Enable CNAM, SHAKEN/STIR, and Voice Integrity to improve deliverability and avoid spam labels
