VoIP

VoIPVoIP – also known as Voice over IP or Voice over Internet Protocol – usually refers to the transmission of voice phone calls over the internet.

VoIP is a term for the protocol (method or procedure) by which voice calls are sent over the internet, hence the term Voice over IP. Internet phone communications include more than just voice traffic—with internet fax and text messaging also being a part of “telephony”— but Voice over IP is the main use. The main alternative is the PSTN, or Public Switched Telephone Network, which is made up of the copper wires and switches we’ve used for many years for standard telephone calls. In general, VoIP PBX is thought to allow the ability to offer more features at a lower cost than PSTN telephony. See voice over IP for more information on IP PBX systems.

At VirtualPBX, we believe the choice between VoIP and PSTN is up to the person or company doing the implementation. A VoIP PBX system usually has strong advantages in cost but requires broadband internet connectivity, while the PSTN incorporates landlines, cellular phones, and more. Good business VoIP PBX solutions enable PSTN telephony, as well as Voice over IP. Every VirtualPBX system supports both, in any configuration.
