I am in the process of looking into swapping from a hosted phone platform to something on-prem, primarily due to the internal paging system needing to function even if there isn't an active internet connection (in the event of a fire for example).
Currently our hosted system has worked great for everything except the paging system - constant 'unanswered' calls that require the paging device be power cycled before it works again, support has not been able to assist.
So now I'm pushing to go on-prem (even though I don't particularly want to support an on-prem system...) from a safety perspective due to how unreliable the paging system has been because of the hosted solution.
Can anyone recommend me a relatively simple to manage on-prem solution that has active support? No free/open source options please - we need to be able to contact an "expert" for assistance if required (and be able to point a finger their way if something breaks).
I haven't had to work with on-prem systems in many years - last things I remember managing were 3CX and some Avaya system that I don't recall the name of. Have been happily using cloud hosted services until this issue with the paging system being critical came up.
More than happy to spend (my boss's) money on new hardware to support this - just needs to be a rock-solid solution.
Also, I am guilty of using this subreddit as a "catch-all" for all things "System Administration" related, so if there is a better sub for this question please point me in that direction and I'll post over there.
