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
