Once inside the Static menu, input the static IP address gathered at the beginning of this guide. The phone requires you to
use 3 digits for each part of the static IP address you are entering. This means if you have the IP address of 192.168.1.5,
you need to enter it into the device as 192.168.001.005.
Once the static IP address has been entered, use the directional pad to scroll down. If this is done correctly the phone
should display Subnet Mask.
