Hi,


I'm extremely confused with Cisco IOS versioning system.


We are currently running:

Cisco IOS Software, 3800 Software (C3845-SPSERVICESK9-M), Version 12.4(11)XJ4, RELEASE SOFTWARE (fc2)


on our CallManager Express router.


Any tip to understand and upgrade our system ?

What's the latest version I can use right now ?


I do know how to upgrade routers, I'm only confused about versioning.
