TFTP Downloads
When TFTP is employed, the IP Phone will contact the server provided from the DHCP server
using the name or IP address from DHCP Option #66 or #150 or the TFTP server in memory
when the DHCP option is not available. The IP Phone will request the TFTP server send the
global configuration file ("sysconf_8830_sip.cfg"). Data from an unencrypted file is transferred
to the phone memory. If the file is not readable, the phone attempts to decrypt the file using the
decryption key ("decrypt_key"). If decryption is unsuccessful, an error is logged and the file
ignored.
Changes in the provisioning data from the global configuration file are transferred to the phone
memory and the download process is repeated for the phone-specific configuration file.
Configuration data in the phone specific file overwrites data from the global file.
If a value is changed for a field marked with an asterisk in
“Configuration Parameters” on page D-1
,
the reboot flag will be enabled and the IP Phone will reboot after the download cycle is
completed. By default, the phone specific file uses the MAC address of the phone as the file
name with no file extension.
After completing download of the configuration files, the IP Phone requests the software version
file from the server. This file, which is named "IP_8830_VER_SIP2" is an ASCII text file that
identifies the software version available on the server as well as the names of software files to
be downloaded. The phone compares the software version identified in the file with the version
in the phone. If different, the files identified in the version file are downloaded. Typically, the
files required for download include the main firmware file and an xml file but may include other
files as needed for the upgrade. These files along with the version file are available from
Vertical. If desired, comments may be added to the version file using "#" as the leading
character of the comment line.
If software download is required, the IP Phone will enable the reboot flag and after completing
the download cycle, the IP Phone reboots.
