FIGURE 3: SCREENSHOT OF CONFIGURATION LOG-IN PAGE
The password is case sensitive with maximum length of 25 characters. The factory default password for
End User and administrator is “123” and “admin” respectively. Only an administrator can access the
“ADVANCED SETTING” configuration page.
NOTE: If you can not log into the configuration page by using the default password, please check with
the VoIP service provider. It is most likely the VoIP service provider has provisioned the device and
configured for you therefore the password has already been changed.
After a correct password is entered in the login screen, the embedded web server will respond with the
Configuration pages which are explained in details below.
