Frequently asked questions

A cloud-based private branch exchange is a phone system that has been designed to connect an organisation’s employees to the public switched telephone network using a service that is hosted and managed in the cloud.

Unlike cloud-based systems, traditional PBXs require the use of on-site PBX equipment that needs to be managed and maintained by specialists.

With a cloud-based PBX, there is no need for on-site equipment, reducing upfront costs. It also means that the service can be easily scaled up or down to meet an organisation’s requirements, along with increased security.

Using a cloud-based PBX is ideal for organisations with many locations. With Telviva, they benefit further by being part of a free-call community, allowing for free and seamless inter-branch call transfers.

With Telviva One, users can access the service through a desktop VoIP phone, through a browser on their desktop or laptop, or through a mobile app on their smartphone.
