Your telephone switchboard in the Cloud

Vianova Centrex is a multi-tenant platform dedicated to Vianova Partners.

The platform allows our Partners to provide Vianova Customers with a Cloud PBX service that adapts to businesses of all sizes and levels of complexity: from large organizations with thousands of users that need integration and customization through to call centers, hotels, stores, and small professional practices.

Each Customer gets all the features of an advanced PBX plus the flexibility, scalability, and security of a Cloud solution guaranteed by Vianova.
Centrex benefits from fixed-mobile convergence and, thanks to the integration with Vianova Phone, allows users to use their company extension on their smartphone.

Thanks to their technical skills, hands-on experience and local presence, Vianova’s Partners are able to independently provide the best solutions for the design, sale, rental, installation, billing, and maintenance of the Cloud PBX service based on the Vianova Centrex platform.
