We currently have a 3cx server from our vendor running on Linux and we want to show the number of busy agents. I've tried to read up on this but cannot find any REST documentation (apparently HTTP API was deprecated some time ago). I see the the call-control-api is only available to run on the actual server itself and our server is on Debian and with my limited .NET experience this seems very cumbersome and difficult to get going, especially since we dont even host the actual call server ourselves. (https://www.3cx.com/docs/call-control-api/) How can I expose the call que without using .net ported to run on debian? Can I maybe just take this data from the DB?
