Phone Provisioning
100
[T42S]features.dnd.enable = 0
Custom configuration file:
Linekey.cfg
linekey.2.type=13
linekey.2.line=1
linekey.2.value = 4603
linekey.2.label=Bill
MAC-Oriented configuration files:
001565b09d886.cfg
account.1.enable = 1
account.1.label = Bill
account.1.display_name = 1023
account.1.auth_name = 1023
account.1.user_name = 1023
account.1.password = 1023
account.1.sip_server.1.address = 10.2.1.199
account.1.sip_server.1.port = 5060
3.
Place the configuration files to the home directory of the provisioning server. For example, D:\TFTP Provision.
4.
Specify the configuration files paths in the boot file as desired. For example,
y000000000000.boot
include:config<tftp:/10.2.5.193/CustomSettings.cfg>
[T46S,T48S]include:config “tftp:/10.2.5.193/Linekey.cfg”
001565b09d886.boot
include:config<tftp:/10.2.5.193/Linekey.cfg>
include:config<tftp:/10.2.5.193/001565b09d886.cfg>
5.
Place the boot files to the home directory of the provisioning server. For example, D:\TFTP Provision.
6.
Reboot the phones to trigger auto provisioning.
For the phone with MAC 001565b09d886, it will download the 001565b09d886.boot file, and then download
Linekey.cfg and 001565b09d886.cfg files referenced in the 001565b09d886.boot file in sequence from the pro-
visioning server.
For the phones except for MAC-specific phone, they will request to download the y000000000000.boot file, and
then request to download the referenced files. The phone-specific configuration file Linekey.cfg only applies to
T46S and T48S phones. The only difference is that T46S and T48S phones will download both the two files since
the exclude mode is disabled by default. The other phones will only download the CustomSettings.cfg file.
For the parameter settings in the CustomSettings.cfg file, the phone-specific parameters will only take effect on the
specific phone models.
The following shows the provisioning flowchart for different phone models with phone-specific settings.
