I am running IOS version 12.3(8)T on a 3745 Router that is a voice gateway. My current image is "c3745-ipvoice-mz.123-8.T.bin". I want to upgrade to a more recent and hopefully stable version of code. How do I know which one will work correctly with my config? Can I just look for the same "c-3745-ipvoice-mz..." on version 12.4 train?
Will rate posts.
