# Changes to Caller ID on Forwarded Calls (https://docs.voonami.io/docs/business-voice/changes-to-caller-id-on-forwarded-calls)

## Overview [#overview]

Due to updated carrier requirements, phone systems can no longer pass through the original caller’s phone number when forwarding calls to external numbers (such as mobile phones).

This change is part of industry-wide efforts to reduce call spoofing and enforce caller ID verification standards.

## What Is Changing [#what-is-changing]

When a call is forwarded from your phone system to an external number:

* The **original caller’s number can no longer be reused as the Caller ID**
* Carriers will **block calls that use unverified caller ID**
* Forwarded calls must now use a **verified business number**

## How This Affects You [#how-this-affects-you]

If your system is currently configured to:

* Redirect calls while maintaining the original callers CID
* Forward calls without setting the outbound phone number.

Those calls may begin to:

* **Fail to connect**, or
* Be **blocked by the carrier**

## Available Options [#available-options]

### Option 1: Use a Verified Business Caller ID (Simplest) [#option-1-use-a-verified-business-caller-id-simplest]

Forward calls to external numbers using your main business number as caller ID.

**Pros:**

* Reliable call delivery
* No additional setup for end users

**Cons:**

* Users will not see the original caller’s number
* All calls appear as your business line

### Option 2: Deliver Calls to an Internal Extension (Recommended) [#option-2-deliver-calls-to-an-internal-extension-recommended]

Route calls to a user’s extension instead of forwarding to a cell phone.

Users can then receive calls via:

* Desk phone
* Vodia desktop app
* Vodia mobile app

**Pros:**

* Preserves original caller ID
* Full phone system functionality
* No carrier restrictions

**Cons:**

* Requires an extension for each user
* Initial setup may be needed

## Using the Vodia Mobile App [#using-the-vodia-mobile-app]

For users who need mobility, the Vodia app allows calls to be received on a mobile device while still being treated as an internal extension.

This ensures:

* Caller ID is preserved
* Calls are not blocked by carriers
* Users can make outbound calls with the correct business identity
