I have CME 4.1 and 7945 ver 8.3(2)S
There are two problem;
1) for some menus, navigation button doesnt work correctly.
2) I try to transfer outside call to inside phone, phone doesn't answer,
after ending trasfer ring-back tone continues to play in the backgroung
with my original outside call.
3) User-defined locales does'nt work
Upgrading CME 4.2 solves them?
Can I upgrade 7945 fw to 8.3(4)SR1
8.3(4)SR1 is for CM? or does it work with CME?
12.4(6)XW would be required for the newer phones as it also allow you to configure display lighting timeouts.
Regarding phone FW, it's a bit of a gamble to get it right. Try with the latest available in any case. For user locale, you need to use 7941 files, renaming them to the names used by the 7945 (debug tftp events will show you which names are these).
Hope this helps, please rate post if it does!
I saw a CME 4.1 download which included phone loads for the new phones. I would probably suggest this might solve your problem - I will be trying it on one installation soon as I have ordered some of the same phone.
