Changing the USB Configuration
When using the USB cable to configure a phone, you might need to change the
USB configuration. The phone has a default USB IP address of 192.168.1.100 that
you can use with the USB connection to the PC. If you need to change the USB
port configuration, these options are available:
• Obtain the IP address automatically, by getting an IP address from the PC
with DHCP set up.
• Use the IP address and subnet mask assigned in this area.
