Editing a device

Initially, when you come to edit a device, you'll reach a Device details tab, where you can find all the configuration options as when adding a new device, with the addition of the option to enable the VPN (currently on supported on Yealink devices) and the administration password at the bottom:

You'll need to use the administration password to login to the phone in your network.

The Additional configuration tab allows you to add extra configuration to send to your device during provisioning. This is highly discouraged unless you are an advanced user who understands the protocols for provisioning that particular device.

Once you've updated any configuration, just click Save to finish.
