Chapter 3      Setting Up the Cisco IP Phone
    Before You Begin
Audio Quality Subjective to the User
Beyond the physical, mechanical and technical performance, the audio portion of 
a headset must sound good to the user and the party on the far end. Sound is 
subjective and Cisco cannot guarantee the performance of any headsets or 
handsets, but some of the headsets and handsets on the sites listed below have 
been reported to perform well on Cisco IP Phones.
Nevertheless, it is ultimately still the customer’s responsibility to test this 
equipment in their own environment to determine suitable performance. For 
information about headsets, see:

Connecting a Headset
To connect a headset to the Cisco IP Phone, plug it into the Headset port on the 
back of the phone. Press the Headset button on the phone to place and answer 
calls using the headset.
You can use the headset with all of the features on the Cisco IP Phone, including 
the Volume and Mute buttons. Use these buttons to adjust the ear piece volume 
and to mute the speech path from the headset microphone.
Disabling a Headset
You can disable the headset through the Cisco CallManager Administration 
application. If you do so, you also will disable the speakerphone.
To disable the headset from Cisco CallManager Administration, choose Device > 
Phone and locate the phone that you want to modify. In the Phone Configuration 
web page for the phone, check the Disable Speakerphone and Headset check 
box.
