Connect your phone

Get your phone ready by installing the components and get it connected to the network and power.

The phone register process varies with deployment ways. Your phone may get registered automatically when you connect it to the network. Otherwise, you must get the activation code from your administrator to register your phone.

Use the information in this section to connect your phone in a wired network.

Your phone supports Power over Ethernet (PoE). If your network supports PoE, an Ethernet connection powers up your phone and connects it to the network. You don't have to connect the shipped power adapter.

1

Connect the shipped handset to the handset port.

2

Insert the foot stand to the slots on the back of the phone.

For you to easily read the screen and eliminate glare on the screen, adjust the foot stand to change the phone to a proper angle.

3

Connect your phone to the network with the shipped Ethernet cable.

Your phone boots up automatically when it connects to the power source.
If your network supports PoE, your phone powers up when you connect it to the network. Otherwise, go to the next step to connect the power adapter.

4

Connect your phone to a power socket with the shipped power adapter.

Your phone boots up automatically when it connects to the power source.
If your network supports PoE, skip this step.

What to do next

Register your phone

Follow the steps in this section to connect your phone in a wireless network.

Phone ports vary by model. The 9851 diagrams used in the following steps show the ports to connect. Locate the right ports on your phone when you set up the phone.
1

Connect the shipped handset to the handset port.

2

Insert the foot stand to the slots on the back of the phone.

For you to easily read the screen and eliminate glare on the screen, adjust the foot stand to change the phone to a proper angle.

3

Connect your phone to a power socket with the shipped power adapter.

Your phone boots up automatically when it connects to the power source.
4

Press Start on the Welcome screen.

5

Choose your wireless network from the list, enter the username and password, and press Apply.

What to do next

Register your phone.

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 phone connects to the corporate network.
  • Your administrator configures your phone on the call control system.

Technical support

Cisco provides around-the-clock technical support services, both online and over the phone to all customers, partners, resellers, and distributors who hold valid Cisco service contracts.

You should have your Cisco.com User ID, Contract, and Serial numbers ready when you contact Cisco Support to prevent any delays with your support request.

In addition, support staff need the following information:

  • Serial number—Every device has a serial number on the back.

  • Time and date issue occurred—Support staff use device logs or cloud metrics to troubleshoot issues. It is helpful to have the approximate local time and date.

  • Device Logs—Support staff may require the device logs to identify the root cause of your issue.

  • A brief description—Include any actions prior to the incident.

Most firmware issues can be resolved by support staff without a Return Material Authorization (RMA). It is best to use the RMA process for hardware issues.
