Getting Started

You must read Product Safety and Security before you install or charge the battery.

Your phone is powered by a rechargeable Lithium ion battery. Before you can use your phone, you must install the battery in the phone and charge the battery.

Your phone needs to connect to the corporate wireless network and the IP telephony network. Your administrator might set up your new wireless phone, or you might have to set it up.

After the phone is set up, you can use the phone.

Turn On Your Phone

Your phone automatically turns the power off when you are not using it to conserve battery power. You need to turn the phone back on in order to use it.

When you turn the phone on, you may need to enter a username and password to access the wireless network. After the phone authenticates and registers with the call control system, the main screen displays and you can make or receive calls.

Procedure

Press and hold Power/End Call until the red LED lights.

Sign In to Your Phone

If you see a sign-in screen when you turn the phone on, you must enter your username and password to access the phone functions. You may also need to enter other information, as required by your wireless security requirements. Contact your administrator for assistance.

Procedure

Step 1	Enter your user ID.
Step 2	Enter your password.

Turn Off Your Phone

To conserve the battery, turn off the phone when you don't need it to make or receive calls.

Procedure

Step 1	Press and hold Power/End Call for 4 seconds.
Step 2	Press Power off.

Lock the Phone Keypad

You can lock the keypad so that you don't press keys by mistake.

Procedure

Press and hold Zero (0) until you see the message that the keypad is locked.

Unlock the Phone Keypad

If you lock the keypad, you need to unlock it to use the phone.

Procedure

Step 1	Press Unlock.
Step 2	Press Zero (0) .

Access Your Voicemail

You can access your voicemail by calling the voicemail system phone number. But, if your administrator has enabled quick access, you can access voicemail with a single button. The button automatically dials the voicemail system for you.

Your voicemail system is separate from the phone. If you need information about the voicemail system phone numbers for internal and external access and other voicemail system information, contact your administrator.

Procedure

Step 1	Press and hold One (1) on the keypad.
Step 2	Follow the prompts.

Self Care Portal

You can customize some phone settings with the Self Care portal web site, which you access from your computer. The Self Care portal is part of your organization's Cisco Unified Communications Manager.

Your administrator gives you the URL to access the Self Care portal, and provides your user ID and password.

In the Self Care portal, you can control features, line settings, and phone services for your phone.

Phone features include speed dial, do not disturb, and your personal address book.
Line settings affect a specific phone line (directory number) on your phone. Line settings can include call forwarding, visual and audio message indicators, ring patterns, and other line-specific settings.
Phone services can include special phone features, network data, and web-based information (such as stock quotes and movie listings). Use the Self Care Portal to subscribe to a phone service before you access it on your phone.

The following table describes some specific features that you configure with the Self Care portal. For more information, see the Self Care portal documentation for your call control system.

Table 1. Features Available on the Self Care Portal
Features	Description
Call forward	Use the number that receives calls when call forward is enabled on the phone. Use the Self Care portal to set up more complicated call forward functions, for example, when your line is busy.
Additional phones	Specify the additional phones such as your mobile phone that you want to use to make and receive calls with the same directory numbers as your desk phone. You can also define blocked and preferred contacts to restrict or allow calls from certain numbers to be sent to your mobile phone. When you set up additional phones, you can also set up these features: Single number reach—Specify whether the additional phone should ring when someone calls your desk phone. Mobile calls—If the additional phone is a mobile phone, you can set it up to allow you to transfer mobile calls to your desk phone or desk phone calls to your mobile phone.
Speed dial	Assign phone numbers to speed-dial numbers so that you can quickly call that person.

Speed-Dial Numbers

When you dial a number on your phone, you enter a series of digits. When you set up a speed-dial number, the speed-dial number must contain all the digits you need to make the call. For example, if you need to dial 9 to get an outside line, you enter the number 9 and then the number you want to dial.

You can also add other dialed digits to the number. Examples of additional digits include a meeting access code, an extension, a voicemail password, an authorization code, and a billing code.

The dial string can contain the following characters:

0 to 9
Pound (#)
Asterisk (*)
Comma (,)—This is the pause character, and gives a 2 second delay in the dialing. You can have several commas in a row. For example, two commas (,,) represent a pause of 4 seconds.

The rules for dial strings are:

Use the comma to separate the parts of the dial string.
An authorization code must always precede a billing code in the speed-dial string.
A single comma is required between the authorization code and the billing code in the string.
A speed-dial label is required for speed dials with authorization codes and additional digits.

Before you configure the speed dial, try to dial the digits manually at least once to ensure that the digit sequence is correct.

Your phone does not save the authorization code, billing code, or extra digits from the speed dial in the call history. If you press Redial after you connect to a speed-dial destination, the phone prompts you to enter any required authorization code, billing code, or additional digits manually.

Example

To set up a speed-dial number to call a person at a specific extension, and if you need an authorization code and billing code, consider the following requirements:

You need to dial 9 for an outside line.
You want to call 5556543.
You need to input the authorization code 1234.
You need to input the billing code 9876.
You must wait for 4 seconds.
After the call connects, you must dial the extension 56789#.

In this scenario, the speed-dial number is 95556543,1234,9876,,56789#.

Buttons and Hardware

Your wireless phone has many buttons and hardware features that you will use regularly. Use the following figure and table to identify the important button and hardware features. The following figure shows the Cisco Wireless IP Phone 8821, but the Cisco Wireless IP Phone 8821-EX is similar in appearance.

graphic of the Line view — Figure 4. Line View

Differences Between Phone Calls and Lines

We use the terms lines and calls in very specific ways to explain how to use your phone. Here is an explanation of the differences.

Lines: Each line corresponds to a directory number or intercom number that others can use to call you. Your phone supports up to six lines. To see your phone lines, press Phone to open the line view. You have as many lines as you have directory numbers with phone line icons in the line view list.
Calls: Each line can support multiple calls, typically up to four calls. Your phone can support up to 24 connected calls, but your system administrator can adjust this number according to your needs. Only one call can be active at any time; other calls are automatically placed on hold.

Here is an example: If you have two lines and each line supports four calls, then you could have up to eight connected calls at one time. Only one of those calls is active and the other seven are held calls.

Out-of-Range Alerts

Your system administrator can configure your phone to send you an audible alert (beep) when you are out of range of the wireless network. When you hear the alert, the (no signal) icon displays on the phone screen.

When you are out of range of the wireless network, you cannot use the phone for features requiring a wireless network connection, such as making and receiving calls.

If your system administrator enabled the out-of-range alert, depending on the configuration, you might hear a beep only once, or every 10, 30, or 60 seconds until you are back within range of the wireless network.

To reconnect to the wireless network after you hear the alert, move to another location until you see the signal icon on the phone screen again.

Phone Batteries

Your phone contains a lithium ion battery. The fully charged battery provides the following hours of service:

Up to 11.5 hours of talk time (depends on phone firmware and charger version)

The following table shows the differences in talk time when you use:

The new 4.35V Cisco Wireless IP Phone 8821 Desktop Charger and Cisco Wireless IP Phone 8821 Multi Charger
The Cisco Wireless IP Phone 8821-EX Desktop Charger and Cisco Wireless IP Phone 8821-EX Multi Charger

Table 6. Comparison of Talk Times
Condition	Original Cisco Wireless IP Phone 8821 Desktop Charger and Cisco Wireless IP Phone 8821 Multi Charger	New Cisco Wireless IP Phone 8821 Desktop Charger and Cisco Wireless IP Phone 8821 Multi Charger	Cisco Wireless IP Phone 8821-EX Desktop Charger and Cisco Wireless IP Phone 8821-EX Multi Charger
Phone charged in charger, with wall adapter, or with USB Phone running Firmware Release 11.0(4)SR3 or earlier	9.5 hours	9.5 hours	9.5 hours
Phone charged in charger, with wall adapter, or with USB Phone running Firmware Release 11.0(5) or later	11.5 hours	11.5 hours	9.5 hours
Spare battery charged in the charging slot	9.5 hours	11.5 hours	9.5 hours

Up to 145 hours of standby time

Battery life depends on a number of factors including:

On time—The battery life is reduced when the phone is turned on. Calls, messages, application use, Bluetooth use, and actions like menu navigation use power.
Scan mode—Your phone can be set up to scan the access points in three different ways (Continuous, Auto, Single AP). If your phone uses Continuous or Auto scan modes, the phone requires more power, which reduces battery talk time.

If you require longer talk times, you will find it useful to have a spare, charged battery.

Caution

The expected lifecycle for a battery is two years. Based on the average usage, this corresponds to approximately 500 charges. You can check the date printed on the battery to calculate the age of the battery. We recommend you to replace the battery when it reaches its end of life.

Bluetooth and Your Phone

You can use a Bluetooth headset with your phone.

Bluetooth connections work best when you're within 3 to 6 feet (1 to 2 meters) from your phone, but you might be able to be as far away as 66 feet (20 meters). The Bluetooth connection can degrade if you have a barrier (wall, door, window), large metal object, or other electronic devices between your phone and the connected device.

To connect a headset to your phone with Bluetooth, you start by pairing the headset with your phone. You can pair up to 5 Bluetooth headsets with the phone. After the headset is paired, the phone connects to the headset when the headset is turned on. The last Bluetooth headset connected with the phone is the headset that the phone uses.

Note

The Cisco Wireless IP Phone 8821-EX has not been tested or certified with any accessories for use in Potentially Explosive Atmosphere.
