# Configure Cross-Site Dialing in Admin Console

## Objective

Configure cross-site dialing in Admin Console.

## Applies To

- Admin Console
- Cross-Site Dialing

## Procedure

Cross-Site Dialing enables users to call by extension between different sites as long as they are configured under the same company (i.e., company's phone system has Cross-Site Dialing enabled). You will need to have administrator rights in Admin Console to set up this feature.

> [!NOTE]
> Note:
> 
> If you require sites with different extension lengths across PBXs, create a case with 8x8 Technical Support to enable.

1. Log in to [**Admin Console**](https://login.8x8.com/).
2. Select **Sites.**
3. Select **Edit** (pencil icon) to the right of the site that you wish to edit. ![2019-08-19_13-47-40.png](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/13059?sv=2026-02-06&spr=https&st=2026-11-03T23%3A13%3A02Z&se=2026-11-04T00%3A13%3A02Z&sr=c&sp=r&sig=M3O5ZWWFspwUyTrqUrAkSN0fqu51UxHcfFBVtO6qnEw%3D)
4. Enter the **Site Code** under *Internal Dial Plan.*
5. Select the desired extension length from the drop-down. You can select an extension of up to nine digits long. ![2019-08-19_13-48-43.png](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/13058?sv=2026-02-06&spr=https&st=2026-11-03T23%3A13%3A02Z&se=2026-11-04T00%3A13%3A02Z&sr=c&sp=r&sig=M3O5ZWWFspwUyTrqUrAkSN0fqu51UxHcfFBVtO6qnEw%3D)
6. Select **Save**.

### Making Extension-To-Extension Calls with Cross-Site Dialing

Though in-site dialing will remain unchanged, users will have to add the **site code** before the **user's extension** to make extension-to-extension calls between sites. We will use the following Site Codes as an example:

- Acme Site A: 20
- Acme Site B: 21

**Calling Examples:**

- **Within Acme Site A**: Sarah dials 1002 to call Jeff
- **Within Acme Site A**: Sarah can also dial 201002 to call Jeff
- **From Acme Site A to Acme Site B**: Sarah dials 211001 to call Rob
