Getting Started3This section provides instructions on how to get ready for auto provisioning. The autoprovisioning process discussed in this guide uses the TFTP server as the provisioningserver.To begin the auto provisioning process, the following steps are required: Obtaining Configuration Information Managing Configuration FilesBefore beginning provisioning, you need to obtain configuration files. There are twoconfiguration files both of which are CFG-formatted. We call these two files CommonCFG file and MAC-Oriented CFG file. The phone tries to download these CFG files fromthe server during provisioning.IP phones also support a local configuration file named as MAC-local.cfg. When a usermodifies configurations via web user interface or phone user interface, theconfigurations will be saved to the MAC-local CFG file on the phone.The MAC-Oriented and MAC-local CFG files are only effectual for the specific phone.They use the 12-digit MAC address of the phone as the file name. For example, if theMAC address of the phone is 0015651130F9, the MAC-Oriented CFG and MAC-localCFG files have to be named as 0015651130F9.cfg and 0015651130F9-local.cfgrespectively. However, the Common CFG file is effectual for all the phones with thesame model. It uses a fixed name “y0000000000XX.cfg” or “y00000000000X.cfg” as thefile name, where "XX" or “X” equals to the first two digits or the first digit (except 0 forSIP-T28P) of the hardware version of the phone model.The names of the Common CFG file for each phone model are:Phone Model Common CFG FileSIP-T28P y000000000000.cfgSIP-T26P y000000000004.cfgSIP-T22P y000000000005.cfgSIP-T20P y000000000007.cfg
