ITERSOURCE

An on-premise VoIP system is a phone system whose equipment - including servers, cables and routers - must be installed and maintained by the company purchasing the system. All hardware associated with a traditional on-premise PBX system is deployed and maintained by a company's IT staff... Some of the most feature-rich systems available, hosted-VoIP services rely on a service provider's hosted-PBX equipment to route a company's voice and data traffic. Calls are routed over the PSTN (public switched telephone network) to the hosted-PBX system... This method is best suited for small and medium-size businesses with limited IT resources and budgetary funds that want the perks of a powerful VoIP system without the hefty price tag.
