I have a 3825 running IOS 12.4(25)T5 and CCME4.1(0)
Now I want to install some IPhone 7965G + 7916.
So, I must upgrade to at least CCME 4.3.
I checked the possible version, and the last is IOS 12.4(24)T + CCME 7.1
Is it a good idea to install this latest version ?
What should I do to upgrade ?
For xhat I think :
First, upgrade IOS :
. download c3825-spservicesk9-mz.124-24.T1.bin
. copy to flash
. change the boot system
. reload. Can I do that. If so, that run with the old ccme ... ?
- after IOS upgrade to ccme 7.1
The only doc i find about that is http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmeinstl.html
But what should I do ?
I find a file named cme-124-24T.zip. It contains lot of file.
The doc say to simpy download the sbn file to the flash... is it enough ? How the router know the version of ccme to load ? no command like "boot system ..."
