Description
—
• Offset a per phone-based configuration that allows a remote IP
phone to display a different time, based on location. The offset is the
time difference, in hours, between the AltiGen system and the IP
phone.
—
• Format a per-phone-based configuration that allows the IP phone to
display the time in one of the following formats: 24 hour (example:
13:15), 12 hour AM/PM (example: 1:15 PM), or AM/PM 12 hour
(example: PM 1:15).
Lets you assign the TFTP server to which the IP phone can connect for
updating firmware when necessary. Enter the IP address of the TFTP
server in the Server field.
To reset the phone and download the latest firmware image, check the
Reset IP Phone and Boot Download check boxes. If you only check
the Boot Download box, the firmware will be downloaded when the IP
phone reboots (power cycles) next time.
Note:
Make sure the TFTP server is running and the new firmware image
is loaded to the correct directory before you reset and download
firmware.
This setting is for a remote IP phone with a private address and behind

information to execute the NAT traversal for the IP phone. The NAT
status and address are read-only fields.

• NAT Address—This is the NAT router's public IP address, as set in the
Extension Configuration window. Read only.
