    I think OnSIP is well suited to be used in any organization that has a stable, reliable internet connection. The service is top notch and I haven't found a competitor that can beat the service. I've recommended the service to other manufacturing businesses and churches. The organizations that have switched have been extremely pleased with the service.

    We have found OnSIP to be just as good if not better than any of the other services we have researched or used. Once again, the value of OnSIP is unbelievable. Our rates at this organization are less than half of what the competitors were charging. I don't see us changing anytime soon.
