Specific Configuration File (SXXXXXXXXXXXX.cfg)
You use the specific configuration file to change phone-specific settings such as user names
and passwords, and Hot Line configurations. Each specific configuration file (one per phone)
is a text file saved as SXXXXXXXXXXXX.cfg on the TFTP server, where the Xs are the 12-
character hexadecimal MAC address of the phone. To create a specific configuration file, use
a text application such as Notepad or SimpleText, or use your favorite word processing
application and save the file as a text file.
Note: If you exceed the number of characters allowed in a field in the specific configuration
file, then the information in that field will be rejected.
Hot Line
When a Hot Line number, SIP URL or an IP address is set up, the 5215 or 5220 IP Phone
automatically dials that number or address when taken off-hook.
To program a Hot Line, access the User Configuration page of the Web Configuration Tool
(see The Web Configuration Tool on page 7).
Media Configuration
To change the Media Configuration settings, access the Media Configuration page of the
Web Configuration Tool (see The Web Configuration Tool on page 7). Media Configuration
settings include parameters for sending and receiving audio signals over the IP network.
