CP-6921 firmware upgrade

Does anyone know how to upgrade the 6900 series firmware from a PC using tftp and dhcp server software?

Is there a step by step process?

TIA.

thanks aman, does it applicable to 6900 series ip phone?

I used to upgrade the 7900 series by tftpd successfully, but 6900 series seems different.

Hi Jun,

I have never tried on 6900 series .Did u try to upgrade 6900 series and facing some problem.?

Thought the procedure would be same as 7900.

Hi aman,

yes, I tried to flash a 6921 ip phone with the same process of 7900 series, but the 6921 has no response even did not get the ip address correctly.
