For smaller businesses and those with access to broadband internet capabilities but no dedicated IT personnel, a cloud solution provides all of the same features that in the past would only have been available to large enterprises.
It is also less of a strain on the purse to implement a cloud system than it is to invest in the capital expenditure of servers and equipment that would sit on-site.
Companies can lower operating expenses and eliminate the risk of technology becoming obsolete by avoiding the need to hire and train technical staff. You would only be required to manage the users, not the equipment, and that's done through a simple, user friendly control panel. The technology and the back end of the phone system is managed by the cloud hosting company.
