Best practice for recording interface SETTINGS_MAX_FILES in FreeBPX 2.10 & later

Hello all,

As FreePBX 2.10 introduced the improvement with call recording so that the recordings are now quick SQL lookups, what is the recommendation regarding the SETTINGS_MAX_FILES parameter in recordings/includes/main.conf.php?

I have found that it seems that the recording interface now uses both the new (fast SQL) method & the old (slow attempting matches) method simultaneously.

Obviously the new method is way, way faster. Is there a way to disable the old method completely so that old recordings are no longer available to listen to via the /recordings interface? Then if we ever needed to go back & listen to an old recording, we could just revert the change to enable the old method again?

If anyone can shed light on this, I would appreciate it.
