Chapter 3 Setting Up the Cisco Unified IP Phone
Installing the Cisco Unified IP Phone
To disable the headset from Cisco Unified Communications Manager Administration, choose Device >
Phone and locate the phone that you want to modify. In the Phone Configuration for the phone, check
the Disable Speakerphone and Headset check box.
Enabling a Wireless Headset
Note The Cisco Unified IP Phone 7971G-GE and 7970G do not support wireless headsets.
By default, the Wireless Headset Hookswitch Control option is disabled. You can enable it in the
Cisco Unified Communications Manager Administration application. Choose Device > Phone and
locate the phone you want to modify. In the Phone Configuration window for the phone, select Enable
for Headset Hookswitch Control.
On the phone, you can verify that the feature is enabled by choosing Settings > Device Configuration
> Media Configuration and verifying that the Wireless Headset Hookswitch Control is set to Enabled.
Refer to the wireless headset documentation for information about connecting the headset and using the
features.
Using External Devices
The following information applies when you use external devices with the Cisco Unified IP Phone:
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 will perform adequately when suitable devices are
attached using good quality cables and connectors.
Caution In European Union countries, use only external headsets that are fully compliant with the EMC Directive
[89/336/EC].
Installing the Cisco Unified IP Phone
You must connect the Cisco Unified IP Phone to the network and to a power source before using it.
