QUESTION Rasberry pi4 4gb how many extension and concurrent calls

[mayoor]

I am looking to install incredible pbx 2020 and am curious will Rasberry pi4 with 4 gb handle 30 extension and 20 concurrent calls.

That will depend on how much audio transcoding is necessary. Without transcoding it may be OK.
Call recording will also affect capacity.

Pi4 not recommended for commercial purpose. use a x86 PC as PBX server if you care about business reputation or your customers

A Pi4 can easily handle 20 calls in most circumstances. If it's something extreme, like all 20 calls transcoding and using tls/srtp it might be stretched.
