I just needing some assistance, I have a client that has Cisco 6921 phones and they are running version 188.8.131.52 and they want to move from SCCP to SIP but i am not getting this to work.
I have firmware for 9.2, 9.3 and 9.4 version but i cannot get the phone to take them it will freeze at 0% and in the TFTP Server Log shows
“<SIP69xx.9-2-1-0.loads>: sent 1 blk, 480 bytes in 0 s. 0 blk resent [01/04 15:15:27.361]
