It is an undeniable fact that an on-premise business phone system involves greater costs as compared to the hosted systems. IP PBX though reduces a great deal of complexity that was involved in dealing with the tradition PBX, yet the cost of its installment are quite high which makes this system unaffordable for small business firms. But now, there is no need to worry. Hosted PBX systems are increasingly being adopted by small business firms since they offer a variety of perks, the most basic of which include reduction in costs and complexity, flexibility, reliability and mobility. These benefits clubbed with the outstanding calling features provide manifold benefits at quite low rates. Thus, if you plan to switch, a hosted solution will offer all the desired benefits at a price that is impressively less.
