-Yes, in some situation "lock" ring, announce and speech volumes will be a subtitle parameter, and actually necessary!

We run into issues when desk phone (eg ip111) placed into classroom is used for normal call but also presenting pre-recorded announcement (BCC) and live announcements (MC)!

This works normally well until "teacher" manually turn announce volume down meanwhile the announce is played!

Mainly because when student doing their examines, they do not what to be disturbed! (make sense)

However then important BCC announce like "Fire" will only be played with lowest possible volume, and that is not good enough!

So an adjustable "lowest" volume setting 1-10 on all available volumes (ring, announce, speech etc.) will give us tools to override situations like this!

Of course via "Template" !

Even better is add a setting to distingue volume depending source (like "Ring filter" but even support calls via BCC and MC), this will bring us more flexibility and powerful alternatives!
