Hello - I have quite a few phones that need firmware upgrades. They are new out of the box, and are running SCCP41.8-3-1S. They won't uprgade to Sccp41-9x; after doing some research I found that I need to upgrade to SCCP41.8-5.2, then they will upgrade to 9x without a problem. I have been trying unsuccessfully all day to set my laptop up as the tftp server, now I just want to get it done. We recently upgraded from CUCM 4.1 to 7.1, and the only firmware release loaded in call manager is v9. I have downloaded all of v8-5-2 files via cco, but I was told to be cautious uploading them because it was possible that the version I put up there will push out to all the phones registered, which will be a "career limiting move" on my part!
Anyway, I was wondering if anyone has had any luck disabling dhcp on the phone, setting up call manager info and ip statically, and for the tftp portion putting in a temporary tftp address. I am using 3comDaemon tftp server for this on my laptop.
Can anyone confirm whether or not uploading the older firmware info to the call manager tftp server will push that out to all phones? I greatly appreciate any help!
