Note: This guide is only compatible with the Panasonic KT-UT123B phones and additional Panasonic KT-UTXXX devices.

The first step when assigning a Static IP address to anything is to gather the information specific for the network it will be connecting to.

    Once the static IP address has been entered in correctly, use the directional pad to scroll down. If this is done correctly the phone should display Subnet Mask.

    Follow the same steps as entering the static IP address. Repeat this for the Default Gateway and DNS Servers. Once all the static IP address information is entered in correctly press the Enter button. Reboot the phone, and it will boot back up using the programmed static IP address.
