This is called"provisioning".2.2.2 Protocols for ProvisioningProvisioning can be performed over HTTP, HTTPS, FTP, and TFTP. The protocol you should use differsdepending on how you will perform provisioning. Normally, HTTP, HTTPS, or FTP is used for provisioning. Ifyou are transmitting encrypted configuration files, it is recommended that you use HTTP. If you are transmittingunencrypted configuration files, it is recommended that you use HTTPS. You may not be able to use FTPdepending on the conditions of the network router or the network to be used.2.2.3 Configuration FileThis section gives concrete examples of the functions of the configuration file and how to manage it.The configuration file is a text file that contains the various settings that are necessary for operating the unit.The files are normally stored on a server maintained by your phone system dealer/service provider, and willbe downloaded to the units as required. All configurable settings can be specified in the configuration file. Youcan ignore settings that already have the desired values. Only change parameters as necessary.For details about setting parameters and their descriptions, see Section 5 Configuration FileProgramming.Using 3 Types of Configuration FilesThe unit can download up to 3 configuration files. One way to take advantage of this is by classifying theconfiguration files into the following 3 types:Type UsageMaster configuration file Configure settings that are common to all units, such as the SIPserver address, and the IP addresses of the DNS and NTP (NetworkTime Protocol) servers managed by your phone system dealer/service provider. This configuration file is used by all the units.Example of the configuration file’s URL:http://prov.example.com/Panasonic/ConfigCommon.cfg42 Administrator Guide Document Version 2015-072.2.3 Configuration File
