Registration
Generally, your system administrator will set the phone parameters beforehand, and performs
centralized deployment on all IP phones. In this case, after the phone starts up, it is ready to use
and the account has been registered already. But if the account is not registered, you should
register it manually. You can register one or multiple accounts on the IP phone.
You can configure one or multiple line keys to associate with an account. For more information,
refer to Configuring Multiple Line Keys per Account for more information.
