Administrator’s Guide for W60P DECT IP Phones86the back of the IP phone. For example, if the MAC address of an IP phone is 00156574B150, thename of the MAC-Oriented boot file is 00156574b150.boot (case-sensitive).Configuration FilesThe configuration files are valid CFG files that can be created or edited using a text editor suchas UltraEdit. An administrator can deploy and maintain a mass of Yealink DECT IP phonesautomatically through configuration files stored on a provisioning server.Yealink configuration files consist of: Common CFG File MAC-Oriented CFG File MAC-local CFG File Custom CFG FileCommon CFG FileCommon CFG file, fixed named y000000000077.cfg, contains parameters that affect the basicoperation of the DECT IP phone, such as language and volume. It will be effectual for all DECTIP phones.MAC-Oriented CFG FileMAC-Oriented CFG file, named .cfg, contains parameters unique to a particular phone,such as account registration. It will only be effectual for a specific DECT IP phone.The MAC-Oriented CFG file is named after the MAC address of the DECT IP phone. MACaddress, a unique 12-digit serial number assigned to each phone, can be obtained from the barcode on the back of the base. For example, if the MAC address of an DECT IP phone is00156574B150, the name of the MAC-Oriented CFG file is 00156574b150.cfg (case-sensitive).MAC-local CFG FileMAC-local CFG file, named -local.cfg, contains changes associated with non-staticsettings that users make via web user interface and handset user interface (for example,updates to time and date formats, ring tones, dial plan and DSS keys). This file generates only ifthe value of the parameter “static.auto_provision.custom.protect” is set to 1.The MAC-local CFG file is also named after the MAC address (the bar code label on the back ofthe DECT IP phone or on the outside of the box) of the DECT IP phone. For example, if the MACaddress of an DECT IP phone is 00156574B150, the name of the MAC-local CFG file is00156574b150-local.cfg (case-sensitive).Note After the provisioning priority mechanism is enabled (configured by the parameter“static.auto_provision.custom.protect”), all older changes made via web/phone user interface willnot be saved in the -local.cfg file. But the older settings still take effect on the phone. Formore information on this parameter, refer to Configuration Parameters on page 106.
