currently have a number of spare Cisco 7911 phones in storage. Generally they will have standard firmware SCCP version 8.3(2). we have upgrade our callmanager from V4.2 to 8.6 (yeah a big jump). Version 4 server is now decomissioned. I need to get the phones to sccp 9.2(3).
Here lies my issue, Yes I am aware I need an intermediary upgrade to 8.5(2), and this is where I am stuck. Can this be done without Callmanger server??
I am using Tftpd32 on my laptop, set the relevant option on DHCP server so that the phone connects to my laptop to copy the required files. The logs state the connection from the phone is recieved and they read request for random files such as CTLSEP001F9E255FA7.tlv or ITLSEP0001F9E255FA7 or XMLDDefault.cnf.xml.sgn all of which come back with "error 2 in system call CreateFile The system cannot find the file specified"
The file looks like a phone MAC address, but not one currently in our Database nor is it the MAC on the phone I am trying to upgrade.
I have downloaded a number of files from Cisco support such as
cmterm-7911_7906-sccp.8-5-2.zip --> this one is referred to as 7911/7906 SCCP IP Phone firmware files only - Compatible UCM versions 4.3.2, 5.1.3, 6.0.1, 6.1.3, 6.1.4, 7.0.2, 7.1.2 and above The file extract out a number of "sbn" and "loads" file types
Any suggestions or links to the correct firmware would be much appreciated.
yeah thx that seems to have sorted it. Although I do have a couple of phones that do not seem to be taking it. they have the Cisco splash screen, in the bottom left corner is a circle with a dot in it. I think a factory reset is required.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
