1.1.6 Mobile Phone Extensions
This feature gives users the freedom to access their telephone extensions
anywhere in the world, regardless of the type of telecommunications device they
are using: cell phone, VoIP, or landline. The “mobile” aspect that the end user can
always be on the move and still receive calls sent to their telephone extension.
1.2 Ways to Manage the X6004
Use any of the following methods to manage the X6004.
• Web Configurator. This is recommended for everyday management of the
X6004 using a (supported) web browser. You can also use the web configurator
for firmware upgrades and configuration backup/restore.
• Command Line Interface. Line commands offer an alternative to the web
configurator and in some cases are necessary to configure advanced features.
• FTP. Use FTP for firmware upgrades.
1.3 Good Habits for Managing the X6004
Do the following things regularly to make the X6004 more secure and to manage
the X6004 more effectively.
• Change the administrator password. Use a password that’s not easy to guess
and that consists of different types of characters, such as numbers and letters.
• Write down the administrator password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it).
Restoring an earlier working configuration may be useful if the device becomes
unstable or even crashes. If you forget your password, you will have to reset
the X6004 to its factory default settings. If you backed up an earlier
configuration file, you would not have to totally re-configure the X6004. You
could simply restore your last configuration.
