business telephone

A system where multiple telephones are used by businesses in an interconnected fashion that allows for features such as call handling and transferring, conference calling, call metering and accounting, private and shared voice message boxes, etc. A business telephone system can range from just a few phones in a small business up to a complex private branch exchange (PBX) system utilized by large businesses.

Business phone systems can function over the Public Switched Telephone Network (PSTN) and/or over the Internet (Internet telephony or VoIP). Business telephone systems can also be delivered as a hosted service (typically referred to as a centrex), which can free companies from having to invest in costly equipment.
