Upgrade
To upgrade software, this phone can be configured with a TFTP server where the new code image
is located. The TFTP upgrade can work in either static IP or DHCP mode using private or public
IP address. It is recommended to set the TFTP server address in either a public IP address or on the
same LAN with the phone.
To configure the TFTP server via the Web configuration interface
Input the admin password to enter the configuration screen. From there, enter the TFTP server
address in the designated field towards the bottom of the configuration screen.
Once the TFTP server is configured, please power cycle the phone.
TFTP process may take as long as 1 to 2 minutes over the Internet or just 20+ seconds if it is
performed on a LAN. Users are recommended to conduct TFTP upgrade in a controlled LAN
environment if possible. For those who do not have a local TFTP server, Hanlong provides a
NAT-friendly TFTP server on the public Internet for firmware upgrade. Please check the Service
section of Hanlong’s Web site to obtain this TFTP server’s IP address.
Directory to configure local TFTP
1.
Unzip the file and put all of them under the root directory of the TFTP server.
2.
The PC running the TFTP server and the UC IP PHONE should be in the same LAN segment.
3.
Go to File -> Configure -> Security to change the TFTP server's default setting from "Receive
Only" to "Transmit Only" for the firmware upgrade.
