Folks, I am new to this forum, and I have started evaluating a2billing to replace an existing home grown billing system of one of my customers.
My question is very simple, this is regarding simple calling card use. For every calling card system you provide toll free access number and many local access numbers. If a customer calls through a toll free number then needs to be charged 1-2 cents more than if he calls a local number, for same destination.
It seems like we can create two rate cards one for toll free and the other for local access. How do we tell a2billing to use appropriate rate card based on the incoming "trunk" ?
