I just need to know if I am getting that voice functionality as that's very important for me switching over as I don't like my current phone solution.

A few other questions.

Can we buy additional user seats? And if so what is the cost?
Can we also buy additional conversations or voice minutes if needed?
How many phone numbers can we have attached to an account? And is it a twillio integration or do we move our number over to intelswift?

Appreciate the answers, I have two businesses. One deeply requires a helpdesk solution for a tour business, the other is a start up consulting company I run so if this solution works well I'll be sending many clients your way.
