Bluetooth Handsfree Profile Audio Gateway

Cisco IP Phones 8851 and 8861 support Hands-free Audio Gateway mode to work with your Bluetooth headset.

Cisco Intelligent Proximity Support

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.

Bluetooth Phone Book Access Profile (PBAP)

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.

Bluetooth Handsfree Profile (HFP)

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:

- Apple iPhone 4 and 5 series

- Samsung Galaxy S4, Note 2, and Note 3 series

IPMA Support

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.

SHA-256 Manufacturing Installed Certificate

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.

- Click Here

- Click Here

The SHA-256 MIC feature has the following support requirements:

- Cisco Unified Communications Manager releases:

- The compatible Cisco Unified Communications Manager releases are Cisco Unified Communications Manager 9.1(2) and later.

- Cisco Unified Communications Manager 8.6(2) support is planned.

- There is no plan to support this SHA-256 MIC on Cisco Unified Communications Manager Release 8.5 or earlier.

- The compatible ACS release is ACS 5.2 and later.

- The compatible SRST release is IOS 12.4(15)T1 and later.

USB Charging

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.

Wi-Fi Client

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.

Attention:
The network administrator must ensure that the AP configuration conforms to local regulatory laws.

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 Click Here , 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.

Limitations and Restrictions

- Bluetooth Phone Book Access Profile Limitations

- Bluetooth Handsfree Profile Limitations

- Phone Behavior During Times of Network Congestion

Bluetooth Phone Book Access Profile Limitations

- 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.

Bluetooth Handsfree Profile Limitations

- 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.

Phone Behavior During Times of Network Congestion

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:

- Administrative tasks, such as an internal port scan or security scan

- Attacks that occur on your network, such as a Denial of Service attack
