Handset; Speakerphone; Headset - Cisco 7942G Administration Manual

Understanding the Cisco Unified IP Phone 7962G and 7942G Components
Each port supports 10/100 Mbps half- or full-duplex connections to external devices. You can use either
Category 3/5/5e cabling for 10-Mbps connections, but you must use Category 5/5e for 100 Mbps
connections.
Use the SW network port to connect the phone to the network. You must use a straight-through cable on
this port. The phone can also obtain inline power from a switch over this connection. See the
Phones to the Cisco Unified Communications Manager Database" section on page 2-8
Use the PC access port to connect a network device, such as a computer, to the phone. You must use a
straight-through cable on this port.

Handset

The wideband-capable handset is designed especially for use with a Cisco Unified IP Phone. It includes
a light strip that indicates incoming calls and voice messages waiting.
To connect a handset to the Cisco Unified IP Phone, plug the cable into the handset and the Handset port
on the back of the phone.

Speakerphone

By default, the wideband-capable 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

The Cisco Unified IP Phone 7962G and 7942G support wideband headsets.
Note
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
page 3-6
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
