What is the purpose of the ANI in agent groups?

I though maybe if i logged into the queue and made an outbound call it would be the ANI from the agent group... I was wrong.

Well, it is a technical thing. Everytime when there is a dial plan, there must also be a ANI. Because the AG probably always redirects calls, it will probably not use the ANI. But maybe one day we have an option that says "keep the ANI", and then the ANI becomes important.

Also for the network identity, the ANI is already important today. When redirecting calls, the AG gets charged for the call.
