Chapter 3 Setting Up the Cisco Unified IP Phone
Understanding the Cisco Unified IP Phone Components
Network Port
The back of the Cisco Unified SIP Phone 3951 has a port that you use to connect
to the network.
Handset
The handset is designed especially for use with a Cisco Unified SIP Phone. It
includes a light strip that indicates incoming calls and voice messages waiting. To
connect a handset to the Cisco Unified SIP Phone, plug the cable into the handset
and the Handset port on the back of the phone.
Speakerphone
By default, the speakerphone is enabled on Cisco Unified IP Phones.
You can disable the speakerphone through the Cisco Unified CallManager
Administration application. To do so, choose
Device > Phone
and locate the
phone you want to modify. In the Phone Configuration web page 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.
