Trivial File Transfer Protocol (TFTP) is the IP address setting used to reboot a phone when the phone requests a download of its configuration file and firmware. The TFTP/Config Server article, which provides the IP addresses used for programming your phones, is organized by the instance (cluster) that is assigned to your organization.
To change the TFTP address on the Cisco model 7937 phones used in your Sky phone system, use the following instructions:
- Press the Globe button to the left of the keypad.
- Press 2 for Settings, and then 2 for Network Configuration.
- If the padlock in the upper right corner of the screen is locked, press * * # to unlock.
- Scroll to option 15. If it is set to No, press the Select soft key.
- Using the up and down arrows, choose Enable and then press the Select soft key.
- Scroll to option 13 and press the Select soft key.
- Use the back arrow soft key (<<).
- Use the keypad to type the TFTP address to equal the value of your desired cluster.
Make sure to type the periods (.) that separate the numeric TFTP values. - Press Validate and then Save.
Your phone will now reboot with the TFTP address you have entered.
