Reassign an Extension to a Provisioned IP Phone/Gateway

When a device has already been provisioned but its owner changes, or a gateway port needs to serve a different line, you can swap the extension bound to that phone or port without provisioning it from scratch. The following procedures cover both IP phones and gateways.

Reassign an extension to a provisioned IP phone

Sign in to the Cloud Voice management portal and go to Auto Provisioning > Phones, then open the phone you want to change for editing.
Under Assign Extension, choose the extension you want the phone to use.

If the extension you’re after doesn’t appear in the drop-down, it may already be tied to another phone or gateway. You can either release it from the device it’s currently bound to, or, if you want the extension to ring on several endpoints at once, allow multiple registrations for the extension number.
Click Save.

The extension registers on the phone automatically, and the settings from the assigned template are pushed to the device.

Reassign an extension to a provisioned gateway

Sign in to the Cloud Voice management portal and go to Auto Provisioning > Gateways, then open the gateway you want to change for editing.
Under Assign Extension, pick the extension for the port you want to reassign.

If the extension you’re after doesn’t appear in the drop-down, it may already be tied to another phone or gateway. You can either release it from the device it’s currently bound to, or, if you want the extension to ring on several endpoints at once, allow multiple registrations for the extension number.
Click Save. Cloud Voice builds a new configuration file for the gateway and asks whether you want to reboot it.
Click OK to reboot the gateway and apply the changes.

Rebooting takes the gateway offline for a short time, which drops any calls in progress on its ports. When you can, reassign and reboot during a maintenance window or a quiet period.

Once the gateway comes back up, the extension is registered on the selected port.
