> Does it mean if I had a rooted phone I could get the call recording working on latest Android?
Some phone hardware architecture can't let the AP (the Processor running Android) access the call audio (because the audio stream is routed directly from the mic/speaker to the modem).
On those no amount of root hacking will allow you to record calls.
Nevertheless this is rare nowadays where all the audio goes through an ADSP connected to the AP.
Your best bet is to find a phone manufacturer/vendor that advertise call recording support. Alternatively search on call recording website like [1] which phone they support rooted.
