Cisco Unified IP Phone 7821/7841/7861 Alternate Firmware Format
The Cisco Unified IP Phone 7821/7841/7861 firmware version 10.1(1) is also supplied in a zip file as an alternative, in case a Cisco Unified Communications Manager is not available to load the installer program. The name of this file is: cmterm-78xx.10-1-1-9_REL.zip.
After unzipping the firmware files, they should be manually copied to the appropriate directory on the TFTP server.

5. Contact TFTP server for configuration: The IP Phone then contacts the Cisco TFTP server. The TFTP server has configuration files (.cnf file format or .cnf.xml) for telephony devices, which define parameters for connecting to Cisco CallManager. The TFTP server sends the configuration information for that IP Phone, which contains an ordered list of up to three Cisco CallManagers. In general, any time you make a change in Cisco CallManager that requires a phone (device) to be reset, a change has been made to the configuration file of that phone. If a phone has an XML-compatible load, it requests an XMLDefault.cnf.xml format configuration file; otherwise, it requests a .cnf file.
If you have enabled auto-registration in Cisco CallManager, the phones access a default configuration file (sepdefault.cnf.xml) from the TFTP server. If you have manually entered the phones into the Cisco CallManager database, the phone accesses a .cnf.xml file that corresponds to its device name. The .cnf.xml file also contains the information that tells the phone which image load that it should be running. If this image load differs from the one that is currently loaded on the phone, the phone contacts the TFTP server to request the new image file, which is stored as a .bin file.
Using Cisco IP Phones with a DHCP Server
Enterprises with small branch offices that implement a Cisco IP Telephony Voice over IP solution typically implement Cisco CallManager at a central office to control Cisco IP Phones at small branch offices. This implementation allows centralized call processing, reduces the equipment required, and eliminates the administration of additional Cisco CallManager and other servers at branch offices.
Cisco IP Phones download their configuration from a TFTP server. When a Cisco IP Phone starts, if it does not have both the IP address and TFTP server IP address preconfigured, it sends a request with option 150 or 66 to the DHCP server to obtain this information.
•DHCP option 150 provides the IP addresses of a list of TFTP servers.
•DHCP option 66 gives the IP address or the hostname of a single TFTP server.
