2. Foot stand

Supports your phone standing on a desk.

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.

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.

the graphic for installing handset

2

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

The foot stand is designed for two tilt angles. Try both tilt angles to find the best position for your viewing preferences. To switch to the other angle, unplug the foot stand, flip it over, and reinsert it to the slots.

the graphic for installing footstand

3

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

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

(Optional) Connect your phone to a power socket with the power adapter that you purchased separately from Cisco.

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.

Only Cisco Desk Phone 9861 and 9871 support network connection via Wi-Fi. Cisco Desk Phone 9841, 9851, 9861NR, and 9871NR don't support Wi-Fi.

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: 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.

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.
1

Select Start on the Welcome screen.

If you don't take any action, the phone goes to the next step at timeout.

Your phone tries to connect to the network. If you use the wireless network, perform the next step. Otherwise, skip it.

(Optional) Choose your wireless network from the list, enter your credentials, and select Apply.

Cisco Desk Phone 9841 and 9851 don't support Wi-Fi.
3

Select Next when the screen displays that your phone successfully connects to Ethernet or WiFi.

If you don't take any action, the phone goes to the next step at timeout. Then the phone starts checking the configuration, and then starts the registration automatically.

If you are prompted to choose a call service, do one of the following actions:
  • If your phone will be registered on the Cisco Unified Communications Manager (Unified CM), select Cisco UCM > Register.
  • If your phone will be registered on the Webex Calling, select Cisco cloud service > Register.
Contact your administrator if you don't know which service to select.

Typically, the registration takes about 3 minutes depending on the network condition.

After the registration succeeds, your primary line name or number displays on the top left of the phone screen.

4

When the registration is complete, you will be prompted to enable or disable the noise removal feature.

If you don't take any action, the phone enables the feature at timeout.
This feature can filter out background noises during a call. If you choose to disable the feature now, you can still enable it later.

After your phone boots up, it checks the configuration automatically, and you will be prompted to enter an activation code. If you don't have a new activation code, contact your administrator.

Activation codes are used to set up your new phone. They can only be used once, and expire after 1 week.

You might be prompted to choose a call service during the registration, depending on your network condition and your administrator's configurations on the call control system.

Before you begin

  • You have turned on your phone.

  • Your phone connects to a wired or wireless network.

  • Get a 16-digit activation code from your administrator.

If you don't take any action, the phone goes to the next step at timeout. Then the phone starts checking the configuration, and then starts the registration automatically.

If you are prompted to choose a call service, do one of the following actions according to your network environment and the platform where the phone will be registered:
  • If your phone connects to the corporate network and will be registered to the Cisco Unified Communications Manager (Unified CM), select Cisco UCM > Register.
  • If your phone connects to the corporate network and will be registered to the Webex Calling, select Cisco cloud service > Register.
  • If your phone uses Mobile and Remote Access (MRA) to connect to the corporate network when it's away from the office, select Cisco cloud service > Register.
Contact your administrator if you don't know which service to select.
4

When prompted for an activation code, enter your activation code, and select Activate.

Your phone starts the registration immediately. Typically, it takes about 3 minutes depending on the network condition.

After the registration succeeds, your primary line name or number displays on the top left of the phone screen.

5

When the registration is complete, you will be prompted to enable or disable the noise removal feature.

7

Select Apply.

The registration starts automatically. If your phone requires an activation code to continue, do the following:
  1. Get an activation code from your administrator if you don't receive it yet.

  2. Enter your activation code, and select Activate.

Typically, the registration takes about 3 minutes depending on the network condition.

After the registration succeeds, your primary line name or number displays on the top left of the phone screen.

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.

You can find a list of Cisco worldwide support centers at https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html.

Cisco one-year limited hardware warranty terms

Special terms apply to your hardware warranty and services that you can use during the warranty period.
