Cisco IP Phones 8841, 8851, and 8861 |
SIP |
Cisco Unified Communications Manager 8.5(1) and later Cisco Unified Communications Manager DST Olsen version D or later SRST 8.0 (IOS load 15.1(1)T) and above CME 10.0 (IOS load 15.3(3)M) and above through Fast-Track |
The Cisco IP Phone 8841, 8851, and 8861 delivers easy-to-use, highly secure voice communications. Cisco Intelligent Proximity integrates telephony features with personal mobile devices. Options, including support for Wi-Fi networks, offer added flexibility.
A comprehensive set of Cisco Unified Communications Manager features are supported.
The following sections describe some of the important phone features. For more information, see http://www.cisco.com/c/en/us/products/collaboration-endpoints/unified-ip-phone-8800-series/index.html.
Cisco IP Phones 8851 and 8861 support Hands-free Audio Gateway mode to work with your Bluetooth headset.
Users can share contacts and call history. They can also move the audio path of active voice and video calls from a personal mobile device to the Cisco IP Phone 8851 and Cisco IP Phone 8861 for a superior audio experience.
The Cisco IP Phones 8851 and 8861 support contact and call history sharing from the mobile cellular device through the Bluetooth PBA profile. A maximum of 1500 contacts can be imported and displayed on Cisco IP Phones 8851 and 8861. Each contact item can have a maximum of 5 numbers with a maximum 30 characters for each number. The allowed contact name is a maximum of 60 characters.
Note | When an Android phone is connected, the user sees an alert pop-up asking whether Phone Book Access is allowed on that Android device. The user must select Allowed within 30 seconds in order to import the Android phone book to Cisco IP Phones 8851 and 8861. |
Note | An iPhone can connect to two Cisco IP Phones 8851 and 8861 at the same time, but only one of the IP phones can access the iPhone phone book. |
Cisco IP Phones 8851 and 8861 support Hands-free Unit mode to work with mobile cellular devices for full telephony integration and two-way hands-free audio.
Hands-free Unit mode with mobile cellular devices is only supported on the following devices:
The Cisco IP Phones 8841, 8851, and 8861 support Cisco IP Manager Assistant (IPMA). IPMA is supported on Cisco Unified Communications Manager Releases 9.1(2) SU2 and 10.5.
Support for IPMA on the Cisco Unified Communications Manager Releases 8.6 and 10.0 will be available soon.
IPMA is not supported on Cisco Unified Communications Manager Release 8.5.1 or earlier.
The Cisco IP Phones 8841, 8851, and 8861 use a manufacturing installed certificate (MIC) with the signature algorithm of SHA-256 with an RSA 2048 key. The signature algorithm requires Cisco Unified Communications Manager, ACS, and Secure SRST support.
The Cisco certificate authority issuing the MIC for this series of phones can be obtained from the following links if separate applications are used and these applications need to authenticate MIC from the phone.
The SHA-256 MIC feature has the following support requirements:
The Cisco IP Phones 8851 and 8861 allow users to charge personal mobile devices using the phone USB ports. The following table describes the USB charging specifications for personal mobile devices.
Cisco IP Phone 8851 | Cisco IP Phone 8861 | |
---|---|---|
Smart phone charging |
Yes (802.3af) |
Yes (802.3af) |
Tablet charging |
No (no back USB port) |
Yes (802.3at) |
The side USB port on the Cisco IP Phones 8851 and 8861 only supports slow charging with limited 500mA/2.5W maximum power.
The back USB port on the Cisco IP Phone 8861 supports fast charging up to 2.1A/10.5W maximum power.
Note | When the Cisco IP Phone 8861 is using PoE with an 802.3af switch, the back USB port can only work in slow-charging mode due to the limited power supply from 802.3af switch. |
The Cisco IP Phone 8861 supports campuses with 802.11a/b/g/n/ac WLAN enabled. Customers need to ensure that 12 Mbps is enabled in the WLAN Controller or Access Point (AP) data rate configuration.
We recommend that customers use 5 GHz as there are more channels and less interferers with those frequencies.
The network administrator must ensure that the AP configuration conforms to local regulatory laws.

Before using the phone firmware release on the Cisco Unified Communications Manager, you must install the latest Cisco Unified Communications Manager firmware on all Cisco Unified Communications Manager servers in the cluster.
Step 1 | Go to the following URL:
https://software.cisco.com/download/navigator.html?mdfid=284729655&flowid=75283 | ||
Step 2 | Depending on your phone model, choose Cisco IP Phone 8800 Series. | ||
Step 3 | Choose your phone type. | ||

Step 6 | Select one of the following firmware files, click the
Download or
Add to cart button, and follow the prompts:
| ||
Step 7 | Click the + next to the firmware file name in the Download Cart section to access additional information about this file. The hyperlink for the readme file is in the Additional Information section, which contains installation instructions for the corresponding firmware. | ||
Step 8 | Follow the instructions in the readme file to install the firmware. |
If a Cisco Unified Communications Manager is not available to load the installer program, the following .zip files are available to load the firmware.
Firmware upgrades over the WLAN interface may take longer than upgrades using a wired connection. Upgrade times over the WLAN interface may take more than an hour, depending on the quality and bandwidth of the wireless connection.
Step 1 | Go to the following URL:
https://software.cisco.com/download/navigator.html?mdfid=284729655&flowid=75283 |
Step 2 | Choose Cisco IP Phones 8800 Series. |

Step 5 | In the Latest Releases folder, choose 10.2(1). |
Step 6 | Download the relevant zip files. |
Step 7 | Unzip the files. |
Step 8 | Manually copy the unzipped files to the directory on the TFTP server. See Cisco Unified Communications Operating System Administration Guide for information about how to manually copy the firmware files to the server. |
By default, Cisco IP Phones are set up for the English (United States) locale. To use the Cisco IP Phones in other locales, you must install the locale-specific version of the Unified Communications Manager Endpoints Locale Installer on every Cisco Unified Communications Manager server in the cluster. The Locale Installer installs the latest translated text for the phone user interface and country-specific phone tones on your system so that they are available for the Cisco IP Phones.
To access the Locale Installer required for a release, access http://software.cisco.com/download/navigator.html?mdfid=286037605&flowid=46245, navigate to your phone model, and select the Unified Communications Manager Endpoints Locale Installer link.
For more information, see the documentation for your particular Cisco Unified Communications Manager release.
Note | The latest Locale Installer may not be immediately available; continue to check the website for updates. |
Cisco IP Phones 8851 and 8861 cannot display certain characters in the Contact/Call history imported from a mobile device if those characters are not included in the phone locale.
In this release, Cisco IP Phones 8851 and 8861 do not support the ability to initiate a new call from the mobile contact book through the Cisco Unified Communications Manager VoIP network.
Only one Bluetooth device can be connected with Cisco IP Phones 8851 and 8861 at the same time, either a BT headset or a mobile phone.
Tablet pairing and connecting is not supported in this release.
Due to mobile device OS limitations, some soft clients on a mobile device (for example, Cisco Jabber or Skype) cannot make full telephony integration with Cisco IP Phones 8851 and 8861 for call controls like Answer, End, Hold, or Resume a call. Some known issues include:
The incoming call event sent from mobile soft client to Cisco IP Phones 8851 and 8861 causes the ongoing VoIP call to go on hold automatically.
The call information might not be displayed correctly on Cisco IP Phones 8851 and 8861.
The call session does not disappear on Cisco IP Phones 8851 and 8861 when the Jabber call ends on the mobile device. Jabber version 10.5 and later removes this limitation.
Anything that degrades network performance can affect Cisco IP Phone voice and video quality, and in some cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following activities:
Known problems (bugs) are graded according to severity level. These release notes contain descriptions of the following:
