With a cloud voice over IP (VoIP) service, your business communications stay centrally managed even if your employees are working from home or using different devices. It is a technology for delivering voice and other forms of communication over an Internet Protocol or IP. VoIP providers offer communications services that the business world relies on for collaboration. While research I have come across Acefone(https://www.acefone.com/uk/) that is one of the leading providers of VoIP Solutions offering the services at affordable prices.
