Virtual Receptionist - No Zoom Phones

[cnicholls]

I am troubleshooting our virtual receptionist kiosk; the reception function is set so that multiple users are assigned to receive the call. The calls are not consistently going through. We do not have zoom phones so the action type is "contacts or zoom rooms from the account" and 2-4 users are assigned. How does the system determine what users to call? What happens if someone doesn't answer the call? Is there a way to set it to forward to another account contact?  I would like to have the calls go to multiple account users without having to purchase Zoom phone license or only calling one person per action button.
