I have dial tone, when i dial a number it never rings!! and receiving no calls in. For a business line none of my clients can reach me… or a voicemail…

I hope some of the more experienced members of this forum can chime in to help you on this one. First they will need some basic information.
What type of service to you have? Cable, DSL, etc.
Do you have a Modem/Router combo? Or standalone modem and router?
What is plugged into what?
Are you getting the “Ooma dial tone” ? Or a standard dial tone?
Have you ported your phone number yet?
What kind of phone are you using?
