G G Configure a Bluetooth Device on a Cisco IP Phone 8800 Series Multiplatform Phone Objective The Cisco IP Phone 8800 Series Multiplatform Phones allow you to connect a mobile phone, an analog headset, a Bluetooth headset, and a USB headset simultaneously to your phone. However, you can use only one headset at a time. When you connect multiple headsets to your phone, you can choose the primary audio device to use for a call. The primary audio path for a call is based on the setting that is chosen for the preferred audio device. Note: To learn how to configure a primary audio output device on a Cisco IP Phone 8800 Series Multiplatform Phone, click here. The Cisco IP Phone can connect with up to 50 headsets, one at a time. The last connected headset is used as the default. Pairing is typically performed once for each headset. After a device is paired, the Bluetooth connection is maintained as long as both devices (phone and headset) are enabled and within range of each other. The connection typically reestablishes itself automatically if either of the devices powers down then powers up. However, some headsets require user action to reestablish the connection. The Bluetooth icon on the Graphical User Interface (GUI) of the phone indicates that Bluetooth is on irrespective of whether a device is connected or not. If you have both a Bluetooth headset and a mobile device connected, you cannot use the Bluetooth headset to answer the audio from the mobile device. This article provides instructions on how to configure a mobile phone or a Bluetooth device on your Cisco IP Phone 8800 Series Multiplatform Phone. Applicable Devices | Firmware Version IP Phone 8851 Series | 11.0.1 (Download latest) IP Phone 8861 Series | 11.0.1 (Download latest) Configure a Bluetooth Device on your IP Phone Configure the Bluetooth Settings on your IP Phone Step 1. Press the Applications button on your IP Phone.
