Edistar has consolidated its skill and knowledge in the implementation of systems managed by the Linux operating system and the opensource software platforms (PHP, PostgresSQL, Tomcat, etc.).  At present all the servers (web, application, db and teletext servers) are based on such technology. 

Moreover, since 1996, Edistar has become autonomous in the construction of  its Interactive Voice Response (IVR), acquiring the necessary skills  both in terms  of hardware and software.  Therefore Edistar is able to rapidly activate new IVR depending on the telephone traffic generated and thus guaranteeing maximum flexibility of management with minimzed costs.  In addition, the in-depth knowledge of the platform allows the rapid implementation of any type of application. 

Edistar has built its own internal Multichannel network, in which the various resources are shared and available for each level of integration.  The information can enter from one channel and be transmitted from another, depending on the terminal used by the end user (telephone, fax, pc, mobile telephone or television).

The shared channels, associated with the various telecommunication tools are:

• Voice Channel (fixed and mobile telephony) managed by IVR EdiVoice. 
• Mobile Channel managed by three different Gateways, of which one is connected to the MAM of Vodafone Omnitel and another is connected to Wind. 
• Web Channel managed by a group of systems that supports the sites and all the applications aimed at the Internet. 
• Fax Channel managed by servers capable of simultaneously receiving and transmitting G3 faxes. 
• Teletext Channel (internal subnetwork + geographic network) managed by an appropriate group of servers that support various linear teletext program schedules and the applications of Interactive Teletext of certain important  television broadcasters (Italia7-Telepadova, MTV, La7 and others). 

Resources

Access to the National Telephone Network makes use of the collaboration of  three important telephone operators:  Eutelia, Telecom Italia and Fastweb. 

The possibility of operating directly within a telephone exchange and being connected by fibre optics, allows Edistar maximum flexibility and very rapid expansion capacity. Edistar's structures and the intelligent network resources distributed by telephone operators  are logically and physically interconnected so as to guarantee the maximum utilization of the resources. 

As for connectivity towards the IP world we now have links towards Telecom Italia, Fastweb and Eutelia, with an overall bandwidth of 16 Mbit/s and which is easily expandable.
