Why can I not make phone calls from my Ring Central virtual phone? It is costing me a fortune to have to use my personal phone system to make long distance calls! Meanwhile, all the Ring Cental minutes that have been paid for go unused because half the time the "Ring Out" function is NOT available. (An onscreen notice tries to suggest there is no internet connection which is absurd.) Then it might work, then not. There's no detectable pattern. PLEASE HELP!!!!!
