# Caller ID & Handling

> Learn how to configure and manage caller ID for outbound campaigns

When you launch an outbound campaign, you can choose which number appears on recipients' phones.

## 1. Dedicated Number

* If you've rented a local or toll-free number, you can select it as the "Phone number" in the assistant settings.
* Good for brand consistency or if you also accept inbound calls on the same line.
* **No OTP verification needed** for numbers rented through Kalimna.ai.

## 2. Verified Existing Number (Caller ID Only)

* If you want your personal or company phone line to appear, verify it with an **OTP** or short call.
* This won't handle inbound calls for the AI, but the lead sees that recognized number on caller ID.
* **Note**: OTP verification is ONLY required when using your own existing number as Caller ID.

## 3. SIP Integration

* If you use a PBX or VOIP platform, you might pass a custom caller ID from your existing system.
* Make sure your trunk or provider is set to allow a specific outbound Caller ID.

## 4. Country-Specific Rules

* Some regions prevent using numbers you don't own as Caller ID.
* Always ensure you have the right to present that number to avoid spam or legal issues.

**Tip:** Test by calling your own phone or a friendly colleague to confirm the correct caller ID is displayed before launching a big campaign.
