Speakerphone
By default, the speakerphone is enabled on the Cisco Unified IP Phone.
You can disable the speakerphone by using Cisco Unified Communications
Manager Administration. To do so, choose Device > Phone and locate the phone
you want to modify. In the Phone Configuration window for the phone, check the
Disable Speakerphone check box.
Headset
Although Cisco Systems performs some 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. Because of the inherent environmental
and hardware inconsistencies in the locations where Cisco
Unified IP Phones are
deployed, there is not a single “best” solution that is optimal for all environments.
Cisco recommends that customers test the headsets that work best in their
environment before deploying a large number of units in their network.
In some instances, the mechanics or electronics of various headsets can cause
remote parties to hear an echo of their own voice when they speak to
Cisco
Unified IP Phone users.
Cisco Systems recommends the use of good quality external devices, like headsets
that are 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 cell phones and two-way radios, some audio noise may still
occur. See the
“Using External Devices with Your Cisco Unified IP Phone”
section on page 3-6 for more information.
The primary reason that support of a headset would be inappropriate for an
installation is the potential for an audible hum. This hum can either be heard by
the remote party or by both the remote party and the Cisco
Unified IP Phone user.
Some potential humming or buzzing sounds can be caused by a range of outside
sources, for example, electric lights, being near electric motors, large PC
monitors. In some cases, a hum experienced by a user may be reduced or
eliminated by using a local power cube.
