Nova is a product developed by IVSTEL that is used to control one or more Dialogic Cantata Excel Converged Services Platforms(CSP) or TelcoBridges Carrier Grade Switches or SIP Servers.

Australia’s largest Calling Card companies have used Nova for over a decade to deliver billions of minutes of voice traffic per year.

Nova allows a Service Provider to quickly set up a Pre-Paid Calling Card and Least Cost Routing (LCR) service and offer low cost international calls to customers.

The Service Provider can either sell Calling Cards to the end user directly or use Nova to support resellers (Virtual Network Operators) who sell their branded cards to end users.


Nova also provides other enhanced services such as Single Stage Dialling, Callback, Conference, 1300 Virtual Number, Pre-select, Override and Wholesale Least Cost Routing.

In addition, Nova allows new IVR services to be programmed by the owner using the internal VXML programming language with powerful extensions to access external applications and databases.

Nova provides at it core a Central Real Time Prepaid Billing System, an unlimited number of Java based Operator Consoles for the help desk, replicated SQL databases to provide a scalable and a geographically dispersed system built on a Linux platform.

Nova can run on a single Unix or Linux server and its distributed architecture allows its various functions to be spread over more than one server as your central site grows.

The Nova system is scalable by adding new switches or sites to form a Multi Switch Nova System with a central database.


The central database allows your users to travel but still access the same service from any one of your switches. Importantly, you can deploy geographically remote sites with local switching allowing users to roam without the need to ever trunk calls back to the central site.

And of course, a multi-site Nova system gives you disaster recovery where each site can run independently should the need arise.
