Caution
Use of a cell, mobile, or GSM phone, or two-way radio in close proximity to a Cisco IP Phone might cause
interference. For more information, see the manufacturer documentation of the interfering device.
As with other network devices, you must configure Cisco IP Phones to prepare them to access Cisco Unified
Communications Manager and the rest of the IP network. By using DHCP, you have fewer settings to configure
on a phone. If your network requires it, however, you can manually configure information such as: an IP
address, TFTP server, and subnet information.
Cisco IP Phones can interact with other services and devices on your IP network to provide enhanced
functionality. For example, you can integrate Cisco Unified Communications Manager with the corporate
Lightweight Directory Access Protocol 3 (LDAP3) standard directory to enable users to search for coworker
contact information directly from their IP phones. You can also use XML to enable users to access information
such as weather, stocks, quote of the day, and other web-based information.
