I know that ‘call-limit’ is deprecated in favour of GROUP_COUNT().
In examples over the net I saw that GROUP_COUNT() is used in each extension as a one of first actions.
What is the best way to limit calls amount not per each extension, but per Asterisk process globally? For example, I have 150 DIDs/extensions alltogether and I’d like my Asterisk to handle no more than 300 simultaneous calls. All of them are incoming, no dialing out.
Should I send all calls to some starting context where I will limit the amount of calls globally, and only then send them with GoTo to some other contexts?
