with 3cx, I have 6 extensions, one ring group that rings all, when there is no line/extension occupied, an incoming call can trigger all 6 ring, as expected. However when one extension is in a call/busy, then a new call is coming in, all other 5 extensions ring fine, but the busy extension does not ring or indicate new incoming call, how can I make it ring or indicate a call in the busy extension? I have tried enable "Accept multiple calls" but it doesn't work. some internet search suggest ALLOWUSEBUSYOPTFORGROUP = 1, but I can't find how, please help
