business VoIP


Business VoIP services are commercial-class versions of residential VoIP services that provide small and medium-sized businesses with advanced features and functionality such as private branch exchange (PBX) capabilities, conference calling, desk-to-desk calling, music on hold and automated attendants.

While residential VoIP plans typically feature a flat-rate pricing structure and allow for only one call at a time, most business VoIP and enterprise VoIP providers offer tiered usage plans and support multiple simultaneous calls.

As with all VoIP (or Internet telephony) services, business VoIP uses packet-switched telephony to transmit calls over the Internet as opposed to the circuit-switched telephony used by the traditional Public Switched Telephone Network (PSTN).
