The cost saving that will be the main reason before licenses is the amount of hardware

64 cores of CPU, and total of 4TB of storage;
That is for just basic telephony for around 400 phones with call recording for some with
a mostly non working HA and not to mention the DSP devices for PRI lines and media
resources for phones which is using almost an entire rack.
While this sounds like a riotously inefficient use of hardware per unit of telephony
realised, such inefficiency is not inherent to proprietary systems, nor are superior unit
economics inherent to open-source.
What you're using sounds like it's just bad, assuming that hardware is truly
necessary and isn't just massively overprovisioned. If you're going to make the
argument that you should switch to something less OPEX-intensive, I don't know that I
would base it on the mere fact that the proposed alternative is open-source.
To put this into perspective, to integrate the
telephony system with MS Teams it will cost 70,000$ USD just for installation and basic
configuration just to ring a deskphone when someone calls you on Teams..
Maybe, but--and this is a mere hypothetical, I have no way of knowing--the cost in fully
burdened engineer compensation to implement all those things yourself might be quite a lot
more than $70K.
