By default, the web interface of the Panasonic KX-UT123 is disabled for security purposes.
To enable it, press Setting on your handset and then enter #534 using the keypad. Scroll to Embedded Web and set it to On, and then press Enter.
You will now be able to navigate to the web interface by entering the IP address of the device into your web browser. If you are unsure what this is, press the Setting softkey and scroll to Information Display. Press Enter and scroll to IP Address. This will display the IP address of the unit.
You will be prompted for a password. If you purchased the phone from Gradwell please see this guide for help with logging in.
If you purchased the phone elsewhere then the default login is admin as the username and adminpass as the password. Please ensure that you change this to a more secure login as soon as possible (please see this guide for more information).
The web interface will close down again after 20 minutes or if three consecutive unsuccessful login attempts are made.
