Appendix D. Using the Configuration File
During automated provisioning with the Config. Download flag, section 4.12 enabled, IP Phones
attempt to download a global and a phone specific configuration file from a TFTP or Web server
supporting HTTP/HTTPS. The global files, “sysconf_8820_sip.cfg”, “sysconf_8830_sip.cfg” and
“sysconf_8840_sip.cfg”, are typically for parameters with the same value for all IP Phones
connecting to the server. Parameters such as Network mode, Provisioning, Daylight savings
time mode are typical globally settings.
The phone-specific configuration file as a default uses the MAC address of the phone or WiFi
module when the WiFi module is installed and configured, for the file name, for example
00405a123477. When using HTTP/S, the IP Phone can be assigned with a name for the phone
specific file in place of the MAC address but the MAC address must be included in the file name
or path. Parameters specified in the phone specific configuration file override those defined in
the global configuration file.
Both the global and MAC configuration files can configure any of the parameters of the IP
Phone; the only difference is the MAC file values have priority over the global file. Each is an
ASCII file with parameters (fields) grouped under the various sections of the configuration file,
see Table D-1
. By assigning values after the field name, the IP Phone configuration parameters
are established.
A field listed in the configuration file with no value will return the value of the associated
parameter to default. If a value is changed for a field marked with an asterisk in Table D-1
, the
reboot flag will be enabled and the IP Phone will reboot after initialization is complete. The first
line of the configuration file (global or phone specific) must be “IP88XX configuration information
(v1.0)” as shown in Figure D-1
.
The IP Phone supports SSL and allows assignment of a user name and password to authorize
access to the HTTPS files. In addition, using HTTP/HTTPS the configuration files can be
encrypted using a 32-byte key, which must be assigned to the phone or passed via the
configuration file; the phone will use the 3DES algorithm to decrypt the file.
In DHCP mode, the values from the DHCP server have a higher priority than the values in the
sysconf_88xx_sip.cfg and phone-specific configuration files.
Table D-1
below shows the configuration parameters by Section and Field name along with
descriptive information. Table D-2
shows selections available for the time zones. Figure D-1
provides a blank configuration file. List a field in the configuration file only if the field requires an
assignment other than default. If a field is erased or commented-out, it will have no affect on
the IP Phone memory; the phone will use the existing value in memory. Deleting an unused
field line from the configuration file also reduces traffic between the provisioning server and the
IP Phone during a boot cycle.
