Asterisk 16 Concurrent calls inbound

Hi Guys,

We have built a very stable outbound dialer on Asterisk and do about 150 concurrent calls on a 4 GIG, 2 vCPU’s and average around 15% CPU usage on Ubuntu 18. Do you have any idea what the MAX is I can push for concurrent calls on inbound calls? We are trying to push as much concurrent calls to one single server without the need of an SBC or OPENSIPS…
