Installing Cisco Unified IP Phones
After you have added the phones to the Cisco Unified Communications Manager database, you can
complete the phone installation. You (or the phone users) can install the phone at the users’s location.
The Cisco Unified IP Phone Installation Guide, which is available on cisco.com, provides directions for
connecting the phone handset, cables, and other accessories.
Note Before you install a phone, even if it is new, upgrade the phone to the current firmware image. For
information about upgrading, refer to the Readme file for your phone, which is located at:

After the phone is connected to the network, the phone startup process begins and the phone registers
with Cisco Unified Communications Manager. To finish installing the phone, configure the network
settings on the phone depending on whether you enable or disable DHCP service.
If you used auto-registration, you need to update the specific configuration information for the phone
such as associating the phone with a user, changing the button table, or directory number.
