# Cisco Webex - Change User's Phone Numbers

You can change one or many users' phone numbers through Control Hub. The changes are committed to the users' records in the Webex identity store.

Here are the scope and limitations of this feature:

- You can only change primary phone numbers through Control Hub.
- Enter numbers only as they should be dialled; we don't normalize the number format.
- You cannot change user numbers that were synchronized to Webex from your Active Directory.

Edit the numbers in Active Directory instead. See [**https://www.cisco.com/go/hybrid-services-directory**](https://www.cisco.com/go/hybrid-services-directory) for how to configure and run the AD synchronization.

- You can change numbers for users who have Webex Calling, although this is not the only mechanism you can use for Webex Calling, and you could get conflicts.
- You can change numbers for users who have Cisco Webex Free Calling.
- You can change numbers for users who have Calling in Webex (Unified CM).
- You must not use Control Hub to change numbers for Webex for BroadWorks users.

| Sign in to [**https://admin.webex.com**](https://admin.webex.com/) and click **Users** on the navigation menu. |

| **1** | Find and select the user. When the user details pane opens, open the **Calling** settings (different controls depending on the user's calling type). You'll see the user's number/s. |
| **2** | Change the user's primary number: - Change the value in **Primary Work Number** - Or, if the user has multiple lines: Click **Primary** > **Edit Line** and change the number. |
| **3** | Click **Save**. The user's primary work number is changed in the Webex identity store. You'll see a warning if the number you entered is different to the primary Webex Calling number. If you want to change the Webex Calling number to match, go to **Services** > **Calling** > **Numbers**. |

Webex is a suite of online meeting, web conferencing, and video conferencing applications developed by Cisco.
