# Pause Red Hat SSO Synchronization

When user synchronization is active, Cloud Voice keeps its user records aligned with the source data in Red Hat SSO (Single Sign-On, the identity service that stores your user accounts). If you need that imported information to stop changing for a while, you can suspend the sync rather than remove the integration entirely. Pausing is the safe choice when you only want the current data to hold still, because it keeps the connection and its settings intact instead of tearing the integration down. Follow the steps below to place synchronization on hold.

## Pause the synchronization

1. Sign in to the PBX (Private Branch Exchange, the phone system) web portal and open **Integrations > Collaboration**.
2. Switch off **User Synchronization**.

   :::note
   Turning off this switch only pauses the flow of updates from Red Hat SSO. It does not delete the integration, so you can turn it back on later.

3. Select **Save**.
4. A confirmation dialog appears. Choose how you want the linked extensions handled, then commit the change:

   1. To remove the PBX extensions that belong to the synced users, tick **Delete the PBX extensions in sync with the Users**. Leave it unticked to keep those extensions in place.
   2. Select **Confirm** to apply.

   :::caution
   Ticking **Delete the PBX extensions in sync with the Users** permanently removes those extensions and the phone service tied to them. This cannot be undone. If you are unsure, leave the box unticked so the extensions stay in place.

## What happens next

Synchronization stops, and no further updates flow in from Red Hat SSO.

:::note
While the sync is paused, its behavior is locked in a few ways:

- The **User Synchronization** configuration is preserved but becomes read-only, so you cannot change it until sync is resumed.
- If you chose to keep the associated PBX extensions, those extensions are frozen: you can neither edit their user information nor delete them.
