Chapter 3 Setting Up the Cisco Unified IP Phone
Understanding the Cisco Unified IP Phone 7906G and 7911G Components
Enabling Group Listen Mode on Cisco Unified Communications Manager
Group Listen mode is disabled by default. To enable this mode, you must do so from the Phone
Configuration window in Cisco Unified Communications Manager Administration.
From Cisco Unified Communications Manager Administration, choose Device > Phone and locate the
phone you want to modify. In the Phone Configuration window for the phone (Product Specific
Configuration section), check the Enable Group Listen check box.
If Group Listen mode is enabled, the Monitor feature softkeys are not available on the phone.
Activating Group Listen on the Phone
Group Listen softkeys are displayed if Group Listen mode is enabled by the administrator on
Cisco Unified Communications Manager. However, these softkeys cannot be configured by using the
Cisco Unified Communications Manager softkey template.
• GListen—Activates Group Listen on the phone. Displayed when Group Listen mode is enabled by
the administrator but not activated on the phone. Once Group Listen is activated on the phone (by
pressing GListen), users can deactivate it by hanging up the handset or by pressing GLOff.
• GLOff—Deactivates Group Listen on the phone. Displayed when Group Listen mode is enabled by
the administrator and activated on the phone.
Note If Group Listen mode is enabled in Cisco Unified Communications Manager, the GListen and GLOff
softkeys replace the Monitor and MonOff softkeys on the phone.
Headset
Although Cisco Systems performs internal testing of third-party headsets for use with the Cisco Unified
IP Phones, Cisco does not certify or support products from headset or handset vendors.
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 cell phones and two-way radios, some audio noise
or echo may still occur. An audible hum or buzz may be heard by either the remote party or by both the
remote party and the Cisco Unified IP Phone 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 Using External
Devices with Your Cisco Unified IP Phone, page 3-5, for more information.
Note In some cases, hum may be reduced or eliminated by using a local power cube or power injector.
These environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are
deployed means that there is not a single headset solution that is optimal for all environments.
Cisco recommends that customers test headsets in their intended environment to determine performance
before making a purchasing decision and deploying in mass quantities.
Note The Cisco Unified IP Phone 7906G and 7911G supports wideband headsets.
