VoIP Business Phone Systems are similar to traditional business phone systems except they are designed to deliver voice or video over data networks instead of traditional phone networks. VoIP business phone systems can make calls to the normal Public Switched Telephone Network (PSTN) and cellular networks like their legacy counterparts, but they can also transmit voice and video across LAN's, WAN's and even the internet.
Deploying a VoIP Phone system will help reduce infrastructure costs, administration costs, and long distance expenses (by using Business VoIP Service) thereby lowering total cost of ownership of a business phone system while at the same time avoiding 'vendor lock' by leveraging the flexibility of open standards. The advanced features of a VoIP business phone system offers significant advantages over legacy business phone systems and also enables businesses to realize significant cost savings, have greater mobility, and achieve increased redundancy by using their existing managed networks.
The components that make up a VoIP Business Phone System consists of a server or appliance, an application platform (like 3CX, asterisk, trixbox, etc.), one or more PSTN to VoIP Solutions (optional, but recommended), and VoIP Phones.
