Multiple Servers

Is it possible for me to add another astpp server in FreeSwitch Servers, and I choose where the client will have its calls?

My question would be like this.
Astpp 5 manage customers with dashboard.
Then I can choose whether the client will have the connections on Server 1 or server 2, is this possible, if so how do I do it?

By custom programming it, or contacting support to have them do it for a fee

Hello, I see that you use astpp to manage the clients, but as you do with the PBX functions, as the basic version of astpp does not have any PBX feature, the main thing that would be missing would be the IVR, you do astpp integration with another system with pbx functions?
