If you know what specific feature you are looking for, check out the feature navigator at for a side-by-side comparison of what IOS images have what feature.

If you are looking for a general list of new software features per IOS train, check out the release notes for that particular train:

12.4T -

12.3T -

And so on. Check 12.3 Mainline, 12.2, 12.1, 12.0 etc.

*All* of the new features are listed, not just voice-related. Use a search term like "cross-platform release notes ios 12.3" to find the documents you are looking for.
