External Speakers and Microphone
External speakers and microphones are plug-and-play accessories. You can connect an external PC-type
microphone and powered speakers (with amplifier) on the Cisco IP Phone by using the line in/out jacks.
Connecting an external microphone disables the internal microphone and connecting an external speaker
disables the internal phone speaker.
Using poor quality external audio devices, playing loudspeakers at very loud volumes, or placing the microphone
very close to the loudspeaker may result in undesirable echo for other parties on your speakerphone calls.

Third Party Headsets
Cisco Systems performs internal testing of third-party headsets for use with Cisco IP Phones. But Cisco does
not certify or support products from headset or handset vendors.
Headsets connect to your phone using either the USB or the auxiliary port. Depending upon your headset
model, you have to adjust your phone's audio settings for the best audio experience, including the headset
sidetone setting.
If you have a third-party headset, and you apply a new sidetone setting, then wait one minute and reboot the
phone so the setting is stored in flash.
The phone reduces some background noise that a headset microphone detects. You can use a noise canceling
headset to further reduce the background noise and improve the overall audio quality.
If you are considering a third-party headset, we recommend the use of good quality external devices; for
example, headsets that are screened against unwanted radio frequency (RF) and audio frequency (AF) signals.

Charge Cisco Headset 561 and 562

Depending on the quality of headsets and their proximity to other devices, such as mobile phones and two-way
radios, some audio noise or echo may still occur. Either the remote party or both the remote party and the
Cisco IP Phone user may hear an audible hum or buzz. A range of outside sources can cause humming or
buzzing sounds; for example, electric lights, electric motors, or large PC monitors.
Sometimes, use of a local power cube or power injector may reduce or eliminate hum.
Note
Environmental and hardware inconsistencies in the locations where Cisco IP Phones are deployed mean that
no single headset solution is optimal for all environments.
We recommend that customers test headsets in the intended environment to determine performance before
making a purchasing decision to deploy on a large scale.
You can use only one headset at a time. The most-recently connected headset is the active headset.
Headset Configuration on Your Phone
Cisco Headset 500 Series Customization
The user can customize the headset's gain or microphone volume, sidetone or feedback settings, and test the
microphone. Make sure that the headset is connected to the phone using one of the following connections:
• Cisco Headset 520 Series with the inline USB controller via the USB connector
• Cisco Headset 531 and 532 with the USB adapter via the USB connector
• Cisco Headset 560 Series Standard Base or Multibase with the Y-cable via the AUX and the RJ-9

For information on headset setup, see Cisco IP Phone 8800 Series Multiplatform Phones User Guide.
Set the Upgrade Rule for the Cisco Headset
You can upgrade the firmware of a Cisco headset by connecting it to a Cisco IP Phone Multiplatform Phone.
Before the user performs the upgrade, you must set the upgrade rule on the phone administration web page.
When the headset is connected to the phone, the phone automatically detects the new version of the headset
firmware, then prompts the user to perform the upgrade.
The supported connections for the upgrade are:
• Cisco Headset 520 Series: USB cable
• Cisco Headset 560 Series: USB cable and Y-Cable (RJ-9 and AUX connector)
• Cisco Headset 700 Series: USB cable
The headset settings are not erased by a phone reset. The upgrade rule supports HTTP, HTTPS, and TFTP
protocols.
The release of the Cisco Headset provides the headset XML file that can be used for the firmware upgrade.
If the software version in the file is later than the firmware on the headset, the user is prompted to upgrade
the headset on the phone screen. The user can choose to upgrade the headset immediately or postpone it to a
later time.

Do not change the headset XML file contents.
Caution
For example, tftp://10.74.51.81/prov/headset/1-6-0-162/ciscoheadsetfirmware.xml
You can also configure this parameter in the configuration file (cfg.xml):
<Cisco_Headset_Upgrade_Rule
ua="na">tftp://10.74.51.81/prov/headset/1-6-0-162/ciscoheadsetfirmware.xml</Cisco_Headset_Upgrade_Rule>
Step 4 Click Submit All Changes.
If a new version of the headset firmware is detected, the phone displays an upgrade prompt.
Audio Quality
Beyond 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 we cannot guarantee the performance
of any third-party headset. However, various headsets from leading headset manufacturers are reported to
perform well with Cisco IP Phones.
Cisco doesn't recommend or test any third-party headsets with their products. For information about third-party
headset support for Cisco products, go to the manufacturer's web site.
Cisco does test the Cisco headsets with the Cisco IP Phones. For information about Cisco Headsets and Cisco
IP Phone support, see https://www.cisco.com/c/en/us/products/collaboration-endpoints/headsets/index.html.
Analog Headsets
The phone cannot detect when an analog headset is plugged in. For this reason, the analog headset displays
by default in the Accessories window on the phone screen.
Displaying the analog headset as the default allows users to enable wideband for the analog headset.
USB Headsets
Wired and wireless USB headsets are supported. You can connect one USB headset (or the base station for
a wireless headset) to either the back USB port (if your phone has this port) or to the side USB port.

Wireless Headsets
You can use most wireless headsets with your phone. For a list of supported wireless headsets, see
http://www.cisco.com/c/en/us/products/unified-communications/uc_endpoints_accessories.html
Refer to your wireless headset documentation for information about connecting the headset and using the
features.
Bluetooth Wireless Headsets
For a list of supported headsets, see http://www.cisco.com/c/en/us/products/unified-communications/uc_
endpoints_accessories.html.
Bluetooth enables low-bandwidth wireless connections within a range of 30 feet (10 meters). The best
performance is in the 3- to 6-foot (1- to 2-meter) range. Bluetooth wireless technology operates in the 2.4
GHz band, which is the same as the 802.11b/g band.
Cisco IP Phones use a shared key authentication and encryption method to connect up to fifty headsets, one
at a time. The last connected headset is used as the default. Pairing is typically performed once for each
headset.
Cisco IP Phone Accessories
11
Cisco IP Phone Accessories
Select a USB 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 indicates that Bluetooth is on, regardless of whether a device is connected or not.
Potential interference issues can occur. We recommend 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. Use 802.11a, 802.11n or 802.11ac that operates in the 5 GHz band.
For a Bluetooth wireless headset to work, it does not need to be within direct line-of-sight of the phone.
However, some barriers, such as walls or doors, and interference from other electronic devices, can affect the
connection.
When headsets are more than 30 feet (10 meters) away from the Cisco IP Phone, Bluetooth drops the connection
after a 15- to 20-second timeout. If the paired headset comes back into range of the Cisco IP Phone and the
phone is not connected to another Bluetooth headset, the in-range Bluetooth headset automatically reconnects.
For certain phone types that operate in power-save modes, the user can wake up the headset by tapping on
the operational button to initiate the reconnect.
You must enable the headset and then add it as a phone accessory.
The phone supports various Handsfree Profile features that enable you to use hands-free devices (such as
Bluetooth wireless headsets) to perform certain tasks without handling the phone. For example, instead of
pressing Redial on the phone, users can redial a number from their Bluetooth wireless headset by following
instructions from the headset manufacturer.
These hands-free features apply to Bluetooth wireless headsets that are used with the Cisco IP Phone8851
and 8861:
• Answer a call
• End a call
• Change the headset volume for a call
• Redial
• Caller ID
• Divert
• Hold and accept
• Release and accept
Hands-free devices may differ as to feature activation. Device manufacturers may also use different terms
when referring to a feature.

Only one headset type works at any given time. If you use both a Bluetooth headset and an analog headset
that are attached to the phone, enabling the Bluetooth headset disables the analog headset. To enable the analog
headset, disable the Bluetooth headset. Plugging a USB headset into a phone that has Bluetooth headset
enabled disables both the Bluetooth and analog headset. If you unplug the USB headset, you can either enable
or disable the Bluetooth headset to use the analog headset.
Users can set their Bluetooth headset as the preferred headset, even when a USB headset is connected to the
phone. On the phone, the user selects Applications >Userpreferences>Audio preferences>Preferred
audio device and chooses Bluetooth as the preferred audio device.
