Cisco Cius requires
Cisco Unified Communications Manager to handle call processing. See the
Cisco Unified Communications Manager Administration Guide or context-sensitive help
Cisco Unified Communications Manager application to ensure that
Cisco Unified Communications Manager is set up properly to manage
Cisco Cius and to properly route
and process calls.
Cisco Unified Communications Manager Administration, you can add users to the database and
associate them with specific
Cisco Cius devices. In this way,
users gain access to their
Unified CM User Option
page to configure options for their

Understanding Cisco Cius Components
Cisco Cius includes
these components or accessories:
Cisco Cius includes
one micro-USB port at the top of the unit. Additionally,
Cisco Cius may be used with a
media station, which extends the capabilities of the device and includes three
standard USB ports, two in the back of the unit and one on the right side.
Cisco Cius supports a maximum of
15 devices total connected to the USB ports. Each device that is connected to
Cisco Cius is included in the
maximum device count. Supported accessories include USB serial cable, USB
mouse, USB keyboard, USB-powered hub, and USB memory stick.
The micro-USB port cannot be used to
charge the Cisco Cius mobile collaboration device by connecting to a personal or laptop computer.

Avoid lowering the media station to the lowest level when using a DisplayPort cable. DisplayPort connector damage may result due to forced contact with a desk top surface. Plug the DisplayPort cable in through the hole in the foot stand to prevent the media station from being lowered to the lowest level.
The USB Serial Console allows a USB port on the media station
to be used as a console, eliminating the need for a serial port. The following
table shows the settings for the USB console:
Table 4 USB Console Settings
Cisco Cius comes preloaded
with drivers, Cisco supports only a limited number of cable types. Cisco
recommends using IOGEAR USB-serial adapter.
The USB console cable has a USB interface on one end and a serial interface on the other. The USB interface may be plugged in to any of the three USB ports on Cisco Cius. The serial interface connects to the serial port on the PC.
If you do not have a serial port on your PC/laptop, two USB console cables can be connected back to back, with a Null modem cable between them.
To use a USB console, use the following procedure.
In Cisco Unified Communications Manager, set credentials on device page.
Enable USB debugging under Product Specific Configuration window.
Connect a USB serial cable to Cisco Cius. Cisco Cius console output appears on your terminal screen.
Although Cisco performs internal testing of third-party
headsets for use with
Cisco Cius, Cisco does not
certify or support products from headset or handset vendors.
Cisco Cius reduces
some background noise that is detected by a headset microphone, but if you want
to further reduce the background noise and improve the overall audio quality,
use a noise-canceling headset.
Cisco recommends the use of good-quality external devices, for
example, headsets that are screened against unwanted radio frequency (RF) and
audio frequency (AF) signals. Depending on the quality of headsets and their
proximity to other devices such as mobile (cell) phones and two-way radios,
some noise or echo may still occur. A hum or buzz may be heard either by the
remote party or by both the remote party and
Cisco Cius user. Humming or
buzzing sounds can be caused by a range of outside sources; for example,
electric lights, electric motors, or large PC monitors. See the
Using External Devices, for more
In some cases, you can reduce or eliminate hum by using a local power
cube or power injector.
These environmental and hardware inconsistencies in the
Cisco Cius are deployed means
that there is not a single headset solution that is optimal for all
Cisco recommends that customers test headsets in their
intended environment to determine performance before making a purchasing
decision and deploying them system wide.
Beyond the physical, mechanical, and technical performance, the audio portion of a headset must sound good to the user and to the party on the far end. Sound quality is subjective and Cisco cannot guarantee the performance of any headsets. However, a variety of headsets from leading headset manufacturers are reported to perform well with Cisco devices. See manufacturer sites for details.
Cisco Cius supports 3.5 mm single plug headsets. To connect a wired headset to Cisco Cius, plug it in to the headset port on the bottom of Cisco Cius to place and answer calls using the headset. Single plug wired headsets may also be plugged into the headset port, located on the left side of the media station.
You can use the wired headset with all of the features on Cisco Cius, including the Volume and Mute buttons. Use these buttons to adjust the earpiece volume and to mute the speech path from the headset microphone.
If the headset is analog, see the for the procedure on configuring the wideband codec.
Bluetooth Wireless Headsets
Cisco Cius supports Bluetooth Version 2.1+EDR technology when the headsets support Bluetooth. Bluetooth enables low-bandwidth wireless connections within a range of 30 feet (10 meters). The best performance is in the 3- to 6-foot range (1 to 2 meters). You can pair five or more headsets, but only the last one connected is used as the default.
There can be a potential interference issues. Cisco recommends that you reduce the proximity of other 802.11b/g devices, Bluetooth devices, microwave ovens, and large metal objects. If possible, configure other 802.11 devices to use the 802.11a channels.
For a Bluetooth wireless headset to work, it does not need to be within direct line-of-sight of the Cisco Cius device, but some barriers, such as walls or doors, and interference from other electronic devices could affect the connection.
By default, Bluetooth is enabled for
Cisco Cius on the
Cisco Unified Communications Manager.
To disable Bluetooth from the
Cisco Unified Communications Manager, choose Device > Phone. In the Find and
List Phones window, enter the search criteria for the
Cisco Cius device that you
want to modify, and then select Find. On the Product Specific Configuration
Layout portion of the Phone Configuration window, scroll down to Bluetooth,
click on the Down Arrow and select Disabled.
With Bluetooth enabled on the
Cisco Unified Communications Manager, follow these steps to add the headset as an
Place the headset into discovery/pairing mode.
The procedure for placing a headset into discovery/pairing mode
is specific to the headset. Please see headset manufacturer’s instructions
regarding pairing procedure.
The headset must be in discovery/pairing mode for
Cisco Cius to
successfully pair and connect to the device.
Enable Bluetooth and Bluetooth settings on Cisco Cius, if they are
not already enabled.
To verify whether Bluetooth and Bluetooth settings are enabled,

tries to pair with the headset by using a PIN of
0000. If the headset uses a different PIN, enter
the correct PIN by referring to the user guide that came with the headset.
Cisco recommends that users read the headset user guide for more
information about pairing and connecting the headsets.
If pairing is unsuccessful,
Cisco Cius prompts you
to enter the correct PIN.
Cisco Cius has the correct
PIN, it tries to connect to the accessory.
Cisco Cius provides
feedback to the user while it is trying to connect the accessory. If
Cisco Cius cannot connect,
it displays an error alert to let the user know the reason for the failure. A
timeout of 10 seconds occurs for the
Cisco Cius device to try
to connect the accessory. If the timer expires without a successful connection,
an error alert is shown.
Cisco Cius connects with
headsets using a shared key authentication and encryption method.
Cisco Cius can be
connected with five or more headsets at a time. The last one connected is used
as the default. Pairing is typically performed once for each headset.
After a device has been paired, its Bluetooth connection is
maintained as long as both devices (Cisco Cius and headset) are enabled and within range of each other. The
connection typically reestablishes itself automatically if either of the
devices powers down and then powers up. However, some headsets require user
action to reestablish the connection.
The Bluetooth status indicator indicates whether or not a device
When headset is out of range from the
Cisco Cius, Bluetooth
drops the connection after a 15- to 20-second timeout. If the paired headset
comes back into range of
Cisco Cius (and
Cisco Cius is not
connected to another Bluetooth headset), the in-range Bluetooth headset
automatically reconnects. The user may have to wake-up the headset by tapping
on its operational button to begin the reconnect process.
If a user is actively on a call using a Bluetooth headset, and the
headset is set to off, out-of-range, or is disconnected for any reason, an
alert is presented to either continue the call on the speaker/headset or
disconnect the call. If no action is taken by the user after 30 seconds, the
call is ended.

Important Note about Headset Types
Only one headset type works at any given time, so if you have both a Bluetooth headset and an analog headset attached to the Cisco Cius device, enabling the Bluetooth headset disables the analog headset. To enable the analog headset, disable the Bluetooth headset.
Using External Devices
Cisco recommends the use of good-quality external devices that are shielded (screened) against unwanted radio frequency (RF) and audio frequency (AF) signals.
Depending on the quality of these devices and their proximity to other devices such as mobile phones or two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you take one or more of the following actions:
Move the external device away from the source of the RF or AF signals.
Route the external device cables away from the source of the RF or AF signals.
Use shielded cables for the external device, or use cables with a better shield and connector.
Shorten the length of the external device cable.
Apply ferrites or other such devices on the cables for the external device.
Cisco cannot guarantee the performance of the system because Cisco has no control over the quality of external devices, cables, and connectors. The system performs adequately when suitable devices are attached using good-quality cables and connectors.
In European Union countries, use only external headsets that are fully compliant with EMC Directive 89/336/EC.
Cisco Cius supports external display devices through the micro-HDMI port on the bottom of the device. Connect a monitor to the device by inserting one end of an HDMI cable into the micro-HDMI port and the other end into a monitor HDMI port. The Cisco Cius media station connects to an external monitor through a DisplayPort connection.
Installing Cisco Cius
You must connect
Cisco Cius to the network and
to a power source before using it.
Cisco Cius can be powered
directly through the AC Adapter on
Cisco Cius or through Power
