Rebooting Phones in Bulk via the Hosted PBX Portal
Overview
The Hosted PBX portal includes a Mass Resync feature that lets you reboot one or more phones directly from the portal, without physical access to each device. This is useful when pushing provisioning updates, resolving widespread registration issues, or applying configuration changes across a domain.
Before You Begin
Keep the following in mind before initiating a bulk reboot:
- Phones reboot one at a time, so calls are not all dropped simultaneously
- Some phone models may not fully reboot, but will instead request a new configuration from the provisioning server
- Some models may take a few minutes to complete the reboot process
- Phones that are offline or unregistered will appear greyed out and will be listed as unavailable -- they will not respond to the reboot command
- A scope of Office Manager or higher is required to access this feature
How to Reboot Phones in Bulk

- Log in to the Hosted PBX Portal with a scope of Office Manager or higher.
- Navigate to Inventory > Phone Hardware.
- This is available in the domain-level Inventory view or in the Super User/Reseller main Inventory view when filtered to a specific domain.
- Select the checkbox next to at least one device. The Reboot button will appear in the upper toolbar.
- To reboot all phones in the domain, select the checkbox at the top of the list to select all devices.
- Click Reboot.
- A confirmation window will appear listing the devices to be rebooted. Any unavailable devices will be shown but greyed out.

- Click Reboot again to confirm.
The portal will begin sending reboot signals to each selected device, working through them one at a time.
What Happens Next?
Phones will begin rebooting in sequence. Depending on the number of devices and their models, the full process may take several minutes. Once complete, phones will re-register with the Hosted PBX platform and pull their latest configuration from the provisioning server.
If a phone does not come back online after a reasonable period, check that it is powered on and connected to the network, and confirm that its provisioning settings are correct in the portal.
Still Need Help?
If phones are not responding after a bulk reboot, or if a large number of devices are showing as unavailable, contact UnitedCloud support with the affected domain name and a list of the impacted device MAC addresses.
