I want to build an Asterisk server that is able to deal with as many concurrent calls as possible. Let's suppose that I can buy any hardware available in the market today to set up my server (a top CPU, tons of RAM...), and let's also forget about the network bandwidth restrictions. What would be the theoretical limit of concurrent calls that Asterisk could manage?
I don't need to use any special features, just make outbound calls.
I know that there is no exact answer, so a rough number would be enough.
P.D: I found this link, but it seems pretty outdated:
