We are trying to get our phone to work with a hosted phone system. The phones are all about 6 years old and they consist of 7940, 7960, 7970 and 7934 models. The problem we are running into is that the phones don't seem to want to upgrade to the newer firmware. The 7940's are currently on 7.2 (3.0) and the host is trying to pipe down 8.1 (2.0). I'm told I need to do an intermediate upgrade to 8.0.10 in order for this to work automatically. I was given a file a file called cmterm-7940-7960-sccp.8-0-10.cop.sgn. I'm thinking I can use some shareware TFTP software on a PC to do these upgrades. Does that make sense to and of your Cisco Voip guru's out there?
