MAC-Oriented CFG File

MAC-Oriented CFG file, which is named after the MAC address of the IP phone. For example, if the MAC address of an
IP phone is 00156574B150, the name of MAC-Oriented CFG file is 00156574b150.cfg (lowercase). It contains parameters
unique to a particular phone, such as account registration. It will only be effective for a MAC-specific IP phone.

MAC-local CFG File

MAC-local CFG file, which is named after the MAC address of the IP phone. For example, if the MAC address of an IP
phone is 00156574B150, the name of MAC-local CFG file is 00156574b150-local.cfg (lowercase). It contains changes
associated with non-static parameter that you make via web user interface or phone user interface (for example,
changes for time and date formats, ring tones, and DSS keys).
This file generates only if you enable the provisioning priority mechanism. It is stored locally on the IP phone and you
can upload it to the provisioning server each time the file updates. This file enables the users to keep their personalized
configuration settings, even though the IP phone performs auto provisioning.
Note
The non-static changes that you made before enabling the provisioning priority mechanism are not saved in the generated
MAC-local file, but the previous settings still take effect on the phone. The static changes are never be saved to the
<MAC>-local.cfg file.
The provisioning priority mechanism is enabled by the parameter "static.auto_provision.custom.protect".

Configuration File Customization

You can create some new CFG files by making a copy and renaming the configuration template file (for example,
sip.cfg, account.cfg). You can rearrange the parameters in the configuration template file and create your own con-
figuration files with parameters you want. This flexibility is especially useful when you want to apply specific settings to
a group of phones.

Customizing a Configuration File

Customizing a Configuration File
1. Copy and rename a configuration template file. For example, sip.cfg.
2. Rearrange the parameters in the sip.cfg, and set the valid values for them.
For example:
phone_setting.contrast = 7
local_time.time_format = 1
account.1.dnd.enable = 1
account.2.dnd.enable = 1
features.dnd.enable = 0
3. To specify parameters for specific phone models, add specific phone models in the front of the corresponding para-
meters. Multiple phone model names are separated by commas.
For example:

y000000000052.cfg
y000000000053.cfg
y000000000078.cfg
