I'm trying to make it so client can submit their phone number to a web form and it connects them to one of our representatives. In my ideal world it calls our Round Robin via the MakeCall HTTP API and then whoever picks up gets connected to the target number. First idea: Simply do exactly that. make_call&from=8137074149&to=8008&pin=0909 But this is impossible as you can't make a call from a queue. I imagine it's because you can't specify a password for them so there'd be no security. Second idea: Simple call an extension that has both a pin and is set to forward to the round robin. But no matter what I do, MakeCall doesn't seem to be forwardable by any mechanic. I imagine this is to prevent MakeCall from doing something unagreeable. Can someone steer me in the correct direction for creating such functionality in 3CX? I have a pro license so those features are available to me.
