We recently installed approx. 25 6945 ip phones at our location in Hawaii. Delay seems to be preventing the phones to upgrade firmware. All my work arounds have failed. Any suggestions. Here is what I have tried: Load server - installed all necessary files on local gateway and added tftp-server statements. Created common phone profile and specified ip of local gateway as the load server. Phone load name configured on phone. When I reset the phones they fail to upgrade. This process works for the 7945's and 7965's, but noy for the 6945's running SCCP6945.9-1-1-0.
They do not upgrade using CM as the tftp server using default loads either.
