The cost saving that will be the main reason before licenses is the amount of hardware resources currently used, the system we are using in total is using around 128 GB of RAM, 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.
