Cisco teaches how to record CUCM calls even without having its own call recording solution. Why?

That's interesting. As we're all aware Cisco MediaSense reached its EOL in 2017 with no replacement available from Cisco. All the call recording solutions on the market are developed by 3rd party Cisco Solution Partners. But take a look at CCIE Collab exam topics for 2018 - https://learningnetwork.cisco.com/community/...

The 6.7 section is all about designing and implementing call recording architecture, including SIP recording, built-in bridge and network-based approaches etc etc.

Why? Any suggestions?
