# Phone

> Connecting the agent to a telephony system

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](https://www.twilio.com/docs/voice/branded-calling): 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

<Note>
  **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.
</Note>

## 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**](https://www.twilio.com/docs/trust-hub): Enable CNAM, SHAKEN/STIR, and Voice Integrity to improve deliverability and avoid spam labels
