Register your phone

Depending on how your administrator configures your phone on the call control system, you might use one of the following methods to register your phone:

  • Method 1: No action is required during the phone registration. The registration is done automatically.
  • Method 2: A 16-digit activation code is required during the phone registration. You can get it from your administrator in advance. Enter the activation code when you are prompted for it.
  • Method 3: A service domain and user credentials (user ID and password) are required if you select domain during the phone registration. You can get it from your administrator in advance. Enter the service domain and then user credentials when you are prompted for it.
  • Method 4: An alternate TFTP server address is required if your phone is missing a TFTP address. You can get it from your administrator when this situation occurs. You need to manually enter the alternate TFTP server to continue the registration.
  • During registration, the phone checks the DHCP options in the default sequence of 66, 160, 159, and 150 to obtain the URL of the provisioning server. The first valid configuration response it receives (which includes a 401 authorization request), will determine its provisioning server. Ensure that your server is properly configured to process phone registrations successfully.

  • By default, 802.1X authentication is disabled on your phone.

    If your network uses the 802.1X protocol, ensure that you enable 802.1X authentication on your phone by accessing Settings the Settings key > Network and service > Security settings. Otherwise, your phone will fail to connect to the network.

Your phone gets registered automatically when it boots up and connects to the network. In this scenario of auto registration, you don't need to enter any input as the whole registration proceeds automatically.

Before you begin

  • You have turned on your phone.
  • Your administrator has configured your phone on the call control system.
