Please consider simplifying RC connectivity. There are Phones, Users, Phone Numbers and Licenses. These are all distinct and linking them should be simple and easy to do. Right now this process is very complex, billing is difficult and prompts for charges for what should be free and easy additions, unlinking a phone number from a device can be done in many places is is rather difficult. Temporary numbers are hidden from view and sometimes incur costs long after they should have been removed. Below is a proposal that should simplify their connectivity, possible display location, and work flows etc... Clearly this is a very complex task, I had considered showing example tables, but would not want to dictate any resolution only suggest how it could be improved. Please VOTE, the current process is cumbersome and requires billing access at very low levels of admin tasks. I hope a process change to licensing would allow for easier bulk purchases and pools of licenses, phones and numbers and remove user creation from the billing path.
