Virtual PBX (vPBX) is an IT/Telecom service that simulates the functionality of business phone system. Such a service is delivered over the public switched telephone networks (PSTN) or the Internet, so it belongs to over-the-top (OTT) services.
Usually, virtual PBX service has 3 components: PBX functionality, virtual number, local and long distance phone service.
Virtual PBX service is provided by a service node of service operator. The service node receives calls, makes a routing decision on the basis of a lot of parameters, and forward calls to a new destination through PSTN (Public Switched Telephone Network) or the Internet. The new destination can be a usual landline phone, mobile phone, IP telephone set, softphone.
Virtual PBX service is very popular among entrepreneurs, small and medium business. The reason is that –
- eliminates the need for hardware and software buying
- does not require an attention and resources for maintenance
- perfectly scales with a number of employees, call traffic, needed services, branches
- has a good elasticity to traffic load

Sometimes ‘virtual PBX’ is considered as a synonym for ‘cloud PBX’ and ‘hosted PBX’. Strictly speaking, it is not correct, because these 3 terms emphasize different facets of service. But in most cases these terms are interchangeable.
