Anyone knows really how to configure A2billing at elastix? I see many how to "A2billing" But how to make them interact I can't find. eg> Must I creat provider and add trunk just like I did at outbound route and trunks at elastix? Customers > add customers must be the same extensions at elastix (freepbx)? And call back, and other features? Where can I find how to interact them? Thanks
