I have recently upgraded a customer CCM to version 5.1.3d, which has a default phone load of 8.3.2S for 7911 phones. I am experiencing some issues, which appear to be fixed in release 8.4.2. As a result I am trying to upgrade the firware on the CCM.
I have downloaded the correct signed image from CCO and have installed it into CCM through the Install/Upgrade option under IPTPlatform config. The install goes ahead okay and the MD5 checksums match. I then check the device defaults, and the default phone load has now become the new 8.4.2 version. All good so far. When I reload the 7911's, they still come up with 8.3.2S... I have even tried specifying the SCCP11.8-4-2 load on the phone configuration for a single phone. This results in the phone showing 'error' on the phone when it tries to load the new version, and then falls back to 8.3.2S.
I have upgraded the 7940's and 7960's okay, but the 7911's are proving a challenge!
You are most welcome! All of this stuff is a challenge for me ;-) It seems that any changes that are done in relation to files on the TFTP Server require the Service stop and restart. This is the same if your are changing ringfiles, background images etc. etc. I'm not sure why this isn't spelled out more clearly in the docs, but it is a common issue with all phone models.
