New and Changed Features
Activation Code Onboarding
If your network is configured for Activation Code Onboarding, your administrator generates and provides each user with a unique 16-digit activation code. The user enters the activation code, and the phone automatically registers.
Activation codes can be used only once, and expire after a certain time. If a user enters an expired code, the phone displays Invalid activation code on the screen. If this happens, the administrator provides the user with a new code.
This feature keeps your network secure because the phone can't register until the user enters a valid activation code.
You can change existing phones to use this feature. To do this, reset the phone to the factory settings. After the factory reset and bootup, the phone registers when the user enters the activation code.
